Thank you for that he was able to find some by cross reference, repaired for $85. Will put on tomorrow and hopefully this one will be fixed 🤞

F1 fuse is good and had good voltage at the exciter terminal. At the alternator shop now the diodes are bad, do you have a source for them?

Received and installed Kurt's VR and all is well there, quick shipping, great price and great instructions. Now on the DC charging issue. Voltage reading at the alternator is 23.88 same voltage at the slave terminal. DC amp gauge is slightly in the negative. I have pulled the alternator and...

Thanks for the explanation it helps me understand for next time. Fuse mod checked and is good. I have the fuse and cap mods from your store installed on all of our units that did not have them when we purchased them. I have looked at your replacement VR on eBay this is a direct replacement...

Results from voltage regulator test Step H - 7.2 V Step J - 89.7 V Step L - 121.7 V Step N - ohm range is 0.05 - 4521

I would like to thank all of you for helping me and others in this group. This is the only forum page I am on that you get quick, helpful and civil answers from.

Thank you I will complete the above and report back!

I charged the batteries this morning with another unit, when I disconnected after charging it was at 24.9v. I have only run unit for short periods of time for testing only. The voltage drops slowly and continuously while the unit is running. It has a 20w 24v panel on it.

fuse FU1 is good.

Voltage at the alternator with unit running is 24v - Note, we have a solar 24v chargers on all units and until yesterday have had no issue with any units holding a charge. AC Volt at the outlet with unit running in Prime/Run was 94.2v With adjuster full left - 81.5v at full right - 96.3v...

thanks I will go check it.

So I replaced the faulty oil pressure gauge on the front panel, ( see previous post) the sending unit and installed a manual gauge after the last post. The day after installing the new gauge I have dead batteries, so I jumped the unit with another and it started right up and now have no...

While I am here anybody got any tricks to getting the factory spin-on fuel water separator filter off. Those things I swear are torqued to 150 foot lbs and glued on. The replacements go on and off without an issue but a lot of unsavory language and time has been spent on that one filter.

Update, so I tested the gauge per the TM and it failed. New gauge ordered, and we are adding the pressure gauge above the sender as well ( thanks for those part numbers! ).

Thank you all I have checked wiring all looks good, now to go the the TM troublshooting. these were a great investment for sure. We have 4 803a's, an 802A and a 1060 we just picked up.

Thank you, I will check.

So thanks to the most recent hurricane we ran our MEP 803A for about 113 hours while waiting for power to come back. Now that the power is back on, we decided to service all the generators, just in case it goes back out and change the oil and the fuel filters on this machine change the engine...
