<div class="images-v2-count-0"></div>Had this same issue few years back. It’s just a short somewhere. If I’m not mistaken the one I found was linked the the slav receptacle. Also check the ground on the back of the engine.SGT Ryan KutzThu, 18 Mar 2021 08:54:56 -04002021-03-18T08:54:56-04:00Response by CW2 Private RallyPoint Member made Mar 18 at 2021 9:21 AM

<div class="images-v2-count-0"></div>Get the ole multimeter and wiring diagram out and start checking for the issue. Seems like a short or a resistor that's not resisting.CW2 Private RallyPoint MemberThu, 18 Mar 2021 09:21:43 -04002021-03-18T09:21:43-04:00Response by Lt Col Jim Coe made Mar 18 at 2021 11:35 AM

<div class="images-v2-count-0"></div>If you are a 91D, you should already know the process of troubleshooting why a generator isn't working properly. Pull the FM for the generator, and follow the troubleshooting steps. If you are not a 91D, you are not authorized to do anything about the 10 level maintenance, and should get it into the 3rd shop.SGT Javier SilvaThu, 18 Mar 2021 23:20:08 -04002021-03-18T23:20:08-04:00Response by CPO Michael Hatten made Mar 19 at 2021 12:12 AM

<div class="images-v2-count-0"></div>Is the generator power clean? Some generators put out noisy power with spikes and overvoltages.CPO Michael HattenFri, 19 Mar 2021 00:12:43 -04002021-03-19T00:12:43-04:00Response by SFC Private RallyPoint Member made Mar 19 at 2021 2:53 PM

<div class="images-v2-count-0"></div>Test the voltage regulator using the TM and check the polarity.

<div class="images-v2-count-0"></div>Check your voltage coming out of the GEN, look at the TM and for the troubleshooting steps. Check all wringing on The charging circuit to ensure the are no bare wires exposed or shorted across the ground.SFC Private RallyPoint MemberFri, 19 Mar 2021 15:01:22 -04002021-03-19T15:01:22-04:00Response by SFC Private RallyPoint Member made Mar 19 at 2021 3:18 PM
