Default 74D starts, then dies

I have a 74D 3 wheel Harley. It will turn over and start, but within a few seconds the over voltage circuit breaker will trip. I replaced the circuit breaker and battery. The engine won't run long enough to get output readings from the generator or voltage regulator. Anyone had a similiar problem? Any help is much appreciated.

Default Re: Just a thought

Is it truely running? When we started a 76D cart that had not run in years, we thought it would not run above idle. And then we noticed that the headpipe was cold. So while we thought it was idling, that was all of the starter making it run. It took a while for it to pump old gas from the rear tank and then we finally got the distinct sound of ignition. I just put my multi meter on the battery and with one wheel off of the ground it takes some revolutions beyound idle to make the voltage come up.

It runs, I was actually running it when this happened. There is a distinct difference in sound between when the starter is turning over and when it runs. After it sits for awhile, it will run a bit longer but I haven't gotten a reading off of the generator. Still researching the service manual for those checks.

The overload circuit breaker should not open because of anything to do with the generator. When the key is "ON" and the accelerator peddle is pushed, voltage is simultaneously supplied to the coil, fuel gauge and one of the small studs on the solenoid (voltage to-and-from the starter/generator pass across the large studs and not through the overload breaker).
  1. The overload breaker feeds key switch.
  2. The key switch feeds the accelerator micro switch.
  3. The micro switch feeds the fuel gauge, ignition coil and the starter/run solenoid coil (one of the small connector studs).
  4. The fuel gauge has a ground wire but also feeds the fuel gauge float, which should also be grounded in some way.
  5. The ignition coil feeds the ignition points, which are grounded when closed.
  6. The solenoid coil is grounded by the other small connector stud.
The overload breaker simply takes the place of a fuse for the above circuit(s) and an overcharging generator, or excessive starter draw will not make it open. There can be only two causes for the breaker to open, either a short-to-ground or excessive resistance in the above circuit(s). You will need to isolate each leg of the circuit, and each component, until the problem is diagnosed. I would check ignition coil resistance first, because once you know that is OK you can disconnect, bypass or isolate other parts of the circuit to see if she runs without popping the breaker.

Well... I guess there's always the short-cut method...
You could by-pass the overload breaker, start it up, and wait for the smoke and/or fire to start.

OK, 2 empty fire extinguishers and 5 gallons of water, the fire is out....JK, wire from the micro switch shorted to the choke cable. Runs like a dream once more. Thanks for the help.
