I remember recently a brief mention of a Model T coil tester, and I thought someone was wanting to buy one.

Today I changed out my coil to the flame thrower 40111. My electric tachometer is hooked up to the coil. Now my tac is showing fast for some reason. Any idea why.09-09-2017, 07:11 PM -
When alexiskai came to visit a couple weeks ago, he showed me his Snap On coil tester and also told me about an old school Herbrand coil tester. I then wanted one of my own
After some searching I found a rough and non-working Herbrand tester. In the Chit Chat forum I discussed the Herbrand tester and how I refurbished it.
Putting it to good use, 3 coils were tested. One was an original...08-18-2022, 07:56 AM -

this is kind of a update to a topic i started about timing.During debate we discussed why i had fouled plugs and poor performance. end result was ignition coil. not new but in service less than 6 months. Echlin brand sold through NAPA. i dont have a coil tester but simple Ohms test when cold and when heated with heat gun showed resistance readings that were not consistent. Changed to new coil and...05-21-2019, 12:11 PM -
Can somebody tell me how to check if a coil is good, bad or going ineffective. It's on a 1939 Ford Pickup with the 95HP 239.06-15-2020, 11:29 PM -

HELLO I HAD A PROBLEM WITH A ELECTRONIC DISTRIBUTER SO CHANGED IT TO A POINT DISTRIBUTER . EVERYTHING WAS FINE FOR A WHILE THEN THE MAIN FUSE BLEW OUT AND THE COIL BURNED OUT . I PUT A GENERIC COIL IN IT AND IT WAS GOOD FOR ABOUT A 100 MILES AND IT BURNED OUT ALSO. IS TERE SUPOSE TO BE A RESISTER IN IT?. I AM USING A 12 VOLT SYSTEM WITH A ALTERNATER.

What do ignition coil testers measure ? I’ve seen some very old ones with a ‘good-bad’ meter on them that also allow the high tension wire to plug into the tester. I’m guessing that these testers measure the high voltage generated ??
I’m considering building a simple test device and thinking that I would simply measure the length of the spark produced.

Helped a mate with an electronic Efire crab dizzy today.
Would not go, after a couple of hours we found 2 things wrong.
Firstly the magnet drum had to be pushed right home to work and we could not get a 3 ohm coil to run.
Got it running on a 1.2 ohm coil.
Whether the 3 ohm one is dead or electronics don't like 3 ohms.
12 volt...12-24-2018, 12:50 AM -
