Looking to see what is out there. Really need a transmission spicer 3053 and a transfer case pto for hydraulic pump. Thanks

Merry Christmas too all! And my entry

What are you looking for parts wise?

So removed the vr and looked at the orientation of both q1 and q2. I had soldered q2 wrong so removed and orientated it correctly by schematic. Installed and fired unit up. Voltage is adjustable and correct now. Big thanks to guyfang!

Ran again in run mode voltage is low about 90 volts then when you adjust up it spikes to 178 each leg. I’m wondering if I orientated the transistors q1 and q2 correctly on voltage regulator. Over voltage never trips. Great fun

Found a bent pin in j50 connection. Replaced bridge rectifier with a 20 amp one on a5 board. A4 speared good. Test ran 15 minutes in run. Gained some in Rpms might have to chase that one too. Now to the over voltage problem. 300 volts in 208 mode should have tripped the over voltage...

Wish I knew why it burned out. Maybe the loose transistor on voltage regulator did it

The black square is the bad rectifier

this might cause it to shut down from high voltage causing my run issue. I hope. Will get parts tomorrow.

Pumps are clean. That was the first thing I checked. Great fuel flow in battle short mode. In run mode no power through the k1 relay to pumps. Found cr4 rectifier burned out and r3 overheated. I am still trying to figure out why pumps do not run when the switch s2 is in run mode.

So far Relay k1 operates while battle short engaged but not while run switch on.

The solenoid valve is weak so removed spring for now with new ordered to replace. Found it not working by tapping on it as floats were operated back and forth. Floats work properly to solenoid now but the pumps don’t operate in run mode but only in battle short. The 24v dc circuit must have...

I feel like solenoid for fuel is not allowing fuel to day tank because of no power. Will check tomorrow

I will check this tomorrow. Some history on the unit. The q1 transistor on voltage regulator board was overheated and loose. The fuel gauge pegged full and battle on would generate and run until day tank runs out. Battle off and dies with fuel light on. Soldered q1 transistor back and it...

No fuel

I found the transistor and repairs that but no luck yet. Must have missed a diode?

Mep009b

I know this is an old tread but my Mep009 runs only in battle short. I need the voltage regulator schematic and parts listing. Specifically looking at q1 which was rusted loose but no discernible markings. Help please. Thanks

Count me in I need 4 for my m818! Thanks

If I can find one for a reasonable price. Anyone have any leads on a transfer case pto?
