41 flathead just cuts out when running 😕

[Ken/Alabama]

Check the ignition switch. The contacts inside them get burned and pitted and will heat up causing a high resistance . It's simple to remove and clean it.

Ken, please school me on removal/cleaning contacts for my 33. Thanks

Well, I found out it is was dirty/cracked, may be part of my problem

Ok this is where I stand now with this problem. Today I replaced the ignition switch and ignition brush, new ignition resistor and new starter solonoid, also replaced the condenser which is a napa one IH 200 with the same type ... and wait for it.. nothing! I am not getting spark at all. It won't turn over. I am thinking it's skips coil. Is there a test I can do to the coil to see if it's viable? I have power to the coil from the ignition wire . Battery is good, distributor rebuilt, new plugs and wires .. what the hell am I missing?

had a motor with to thick of paint and did not get good ground at distributor

Is the coils carbon brush making contact with the rotor in the dizzy?....

You can do a resistance check on the coil. One tip on troubleshooting, change one thing at a time, it makes it easier to keep track of what is going on.

Pete, the car started up when we put the new carb on and the new distributor and rebuilt coil. It was going long enough to adjust idle and fuel . I replaced everything due to this problem of starting for a period of time then it would clean cut out mid engine running,like someone had taken the battery cable off. The brush must be making contact with the rotor due to it working long enough to tune the carb.

With the ignition switch on, if you place one lead of your volt meter on the downstream terminal of your resistor and the other lead to ground, should you see 4 volts, and thus a working resistor, regardless of whether the points are open or closed? Thanks

At the downstream side of the ballast resistor (or the ignition side of the coil) you will see6 volts if the points are open; ~4 volts if the points are closed, due to IR voltage drop when current flows from the ignition switch, through the ballast resistor, to the ignition side of the coil, to ground through the points. If you put the voltmeter on the distributor side of the coil, you will again see 6 volts with the points open, and near zero volts with the points closed, because the distributor side of the coil is grounded through the points.

Well the problem was isolated to the coil. I had a phone conversation with skip over the matter and being a true gentleman he took the coil and in no time at all he had it sent back to me, I placed it on the car and she started right up .. thanks to skip for great customer care amd getting the coil back in record time

[Obsolete Jim]

Had a similar problem. Turned out to be the on-off switch was the culprit.

Replace the condenser please,let me know how the helps

hi glen ,the problem turned out to be the coil.I changed the condenser during the diagnotics phase and it still had issues. but its all good now

[glennsanders]

Sorry didn't read all the notes,we just had one. started it ran for 3 mins on manual fuel pump stopped running , turned electric pump on started right up.We figured manual pump bad right.No not that after more trouble shooting is was condenser . Just never know Thanks

[50fordcoupeman]

My problem like that was the coil..............
