I got the control box more or less finished. I made things difficult for myself, but learned a lot in the process. Decided to go with the MEP-018 panel gauges and controls, even though some digital instrumentation would have been easier and more practical. If I were to do this again, I...

Found out from someone on Smokestack forum that the 120/240 is off a 3 phase parallel delta, but taken off as 2 1 phase 120/neutral legs. The configuration is one of the ones in the Lima Mac manual, so I know it is good to go with 1031 12 kw alternator. Now I just need to figure out how I want...

It turns out the connector plug diagram in the MEP-018a TM is transposed from reality(see picture). So in 120/240 single phase; L0= T 5,8. L2= 3,7. L3= 3,11. T 1+12, 4+7, 6+9 are paired together. Still wondering what schematic diagram the single phase hook up would correspond to. But now...

Have found some time to mess with this. I don't understand my results in testing reconnect switch. In 120/240 mode I am getting the following L2= T1 & T9. L3= T8 & T12. L0= T3 & T6. Am using continuity tester from T inputs to output lug. Even if numbering were off, I think I should have 4...

I have studied both the MEP-018a and the Marathon manuals. They both refer to the 12 leads as T-1 though T12. There is no diagram in the 018 manual I have that corresponds to the reconfiguration diagrams in the Marathon manual. I do also have an intact MEP-018, but it needs a bit of work to...

Have not got around to this modification yet. The M1031 12 KW alternator has 12 wires. Will it configure to 12 wire Phase/Voltage selector switch if it is rated for the current? Another way to put this question is; Are the positions and outputs the same for all 12 wire generators ? As in if...

Ok, I have a board from a MEP 018 10 kw genset I bought on e-bay. My main question is; Should I just use switch and output lugs, or would it be good to incorperate elements of board for better quality power, gauges, ect. I want to hook to 120/240 house power and keep 3 ph capability for...

Would the the board or switch from MEP -003 or 004 or any similar 12 lead unit work? In that case it would be a modification others could try as well.

Ok, let me re phrase the original question. If I were to have a qualified professional add a voltage, phase selector switch to a 1031 truck, would a switch for any similar or higher amp MEP 12 lead unit work and would it be wired similarly? I know the generator head can be wired to a 240v...

I was wondering if any of you generator experts could recommend a voltage selector switch to wire into my 1031 truck. It has a 12 kw, 12 lead alternator head. It is wired for 208v, 3 phase. Schematics show it can be reconfigured to other voltage/ phases. As many of the MEPs have switches...
