I'm sorry, but I just don't know how to communicate this any differently. The a/c voltage test is not a static test. The engine has to be turning over to generate the a/c voltage signal. If you're not cranking the engine over while you are checking for ac voltage at the MPU, you will always get...

Hi, just a little clarification. The ohm check is only to check the integrity of the wiring to the MPU and also to check the windings inside the MPU. The proper way to check and set the a/c output voltage on the MPU is while cranking the engine over with the starter. (With good, fully charged...

Speaking from experience it seems like! Yes, those things are touchy from what I’ve discovered.

It's kind of interesting to me. I went back and read some of the information in the TM's about installing and adjusting the MPU. I did find that @Jackal63 is correct. It does mention in https://www.steelsoldiers.com/attachments/15kwmep-804tqg9-6115-643-24p-pdf.602128/ to use an ohm meter across...

I believe that we check the MPU with an a/c volt meter, not an ohm meter. First, remove the MPU from the bell housing for inspection and cleaning. If it doesn’t show any signs of touching the flywheel, no damage to the tip, just clean it and reinstall it. Screw it in by hand until you can feel...
