  • AMP Meter Reading

    Well, first of all this is my first post on VFF. I have a 1931 Fordor DeLuxe Blindback which I recently drove 1080 miles to and from Gettysburg for the 2017 National Meet. I have been hooked on this hobby since 1967, so I was very happy to finally get to a National.

    The Generator on my car is a original 6V unit with a Diode cutout. When the car is started the AMP Meter will usually go to 8 - 10 AMPs charging. After a short period of time it will return to ZERO and stay there for all the time I am driving EXCEPT when I turn on headlights. It will discharge a few AMPs.

    My Question: Is the AMP Meter operating correctly? OR should it be running like the original cutout at about 8 AMPs charging?

    First Wecome here at VFF
    I'm wonder what bulbs you are running
    It sounds pretty normal, charging the battery at first, then 0 when battery is charged, turn lights on slight discharge. If you would be running lights all the time, you could adjust the output of the generator,

      WELCOME to the site.

      Actually, all is well. The purpose of the generator/cut-out is to top the battery off after you start the car and discharge the battery. When this is accomplished, the cut-out will basically back off the charge rate to the battery so you don't boil the water/acid out and cook it. When you turn on the headlights or step on the brake, it takes the top off the battery so the cut-out lets a few pixies travel from the generator to the battery to refill it.

      The few amp discharge is just the loss of a few of those pixies to charge the battery back up by the use of the headlights. As long as the cranking of the starter continues at about the same speed, then you are recharging the battery back to the top.

      Ford, in the Service Bulletins, told the dealers to question the drivers, and if they primarily drove at night, to turn up the charge rate above the normal 10amps so it didn't result in a deeper discharge because the generator/cut-out wasn't filling the battery back up because of the constant headlight usage.

      You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

        Hi Cape
        From what you describe everything sounds normal to me also.
        I'm glad you made it back safe and sound and It was great to finally meet you at Gettysburg

        I moved your post to the main discussion forum... the tech area is for reference and things like that.
        once you spend some time looking around you'll figure it out

          The stock or diode only cut out has nothing to do with the charging rate, It is an on off switch to stop the generator
          from running the battery down when the engine is not running.

            I always thought the diode cutout was a one way switch as Bob said. It sounds to me like you have a voltage regulator in there. My amp meter goes to about 5 amps and stays there. If I turn the lights on it will show a discharge.

              Thanks to all for responding to my first post.
              Also thanks to Mitch for straightening me out where I should be posting questions. I will be putting that jumper in the mail in the a.m. Thanks for the loan.

              As to the question I had, I don't know for sure, but I think the cutout I have is something with Fun in the company name. I don't know if that would change any of the answers
              to my question.

              Big Hammer - I have standard bulbs in the headlights with L.E.D. in the tail lights and directionals.

              Thanks again for the responses!

                Fun projects makes standard cut outs and EVR's. Electronic voltage regulators.

                  How can I tell if I have a Fun Projects product and if it is a standard cut out or EVR?

                    Maybe you can call there and ask how to determine if its an evr or one of their standard cut outs. On those evr's the 3rd brush gets set to about 12 amps and then the regulator adjusts the output.

                  Everything sounds normal, as mentioned, if you have one of the Fun Projects EVR cutouts.
                  You mentioned a jumper wire. I hope you didn't jump across the EVR, as Mr. Regan says it will burn it out.

                    Cape,
                    I presume from your post you made it home safely from the Gettysburg meet. I was concerned about your return trip after you left the repair tent and we were unable to find the cause of your car missing. I tried to PM you on the ***** **** but it said the box was full.

                      battery draw?
                      by thom
                      The generator just quit working on our '28 Coupe so I bought one from a friend that had installed a 6 volt generator on his. Now after about 3 weeks The battery goes dead overnight When the car is running the gauge shows the generator to be charging. I will have to figure out if something (the cutout maybe?) is causing a draw on the battery or if the battery is just no good. Any suggestions?

                      by ClaudeC
                      On my 1933 v8 generator is turning, but is there a way to check to see if it is putting out. When the engine in idle I imagine it would take some time to top of the battery, right?

                      Generator may be Kaput
                      by WMWS
                      Coming home the other day I noticed my ammeter was not showing its usual 5 amps. I checked today and the battery shows 6.4 volts. With engine running about 1500 RPM the Gen output reads 5.2 volts. The cutout output reads 6.4 volts. With engine running 1500 the Gen output reads about 2 amps. If I rev the engine up and down the amp meter in the car goes up to about 5 amps for a few seconds and then...

                      Ammeter always reading negative
                      by Chap52
                      OK here is my current head scratcher. I am running a stock 6 volt positive ground system in my “30 Tudor. I had concerns because the ammeter would always show a discharge of 4-5 amps no matter what the rpm.

                      When I bought the car the previous owner’s son who was selling his deceased Grandfathers “A” had replaced the battery. OOPS, he installed it Negative Ground and drove it a...

                      Proper charge rate?
                      by smittykid
                      I'm running a 6 volt generator on a pos. ground system. I was afraid the old cut out was over charging the battery. I replaced the old cut out with a new NUREX semi-conductor cut out. At regular idle the amp meter shows about 5-6 amps of charge. Running down the road- 40mph it shows around 12 amps charge. No lights on. What is the correct charge rate? Maybe the old cut out wasn't bad after...

                      Battery Charger & Desulfator?
                      by Leo
                      I'm a Battery Tender guy, had one for years and it still does the charging job well. I've read about these desulfator battery chargers which say they can do a better job of prolonging battery life. What say you?

                      by Beauford
                      I thought I had it licked by charging my battery but my gauge still stays pegged at 20. When I first fully charged the battery it would drop to around 10....what's the prob??

                      Question regarding 1926 Model T Re: Battery Polarity Connections
                      by Hank_kirk
                      I am new to this forum and have a question for you guys. When I built my 1926 Model T in 1962 my friend and well known Model T guru, Chris Egsgaard, instructed me to connect the positive battery pole to the frame and the negative pole to the start button. I have had it like that ever since but the car has always cranked slowly. The question is will reversing the polarity help the starter motor...

                      Alternator & Ammeter
                      by dmaxweb
                      For a number of years I've been running a 6V positive ground Alternator with an older repro 20 amp ammeter. I've never had any problems. I have the instrument panel off for re-plating. For safety sake, should I switch to a 30 amp ammeter? If so, now's the time to do it.
