MEP003 Question

[Harleyd315]

I have an 003 that I aquired for our FD. I did all my usual pre start checks and got it running just fine. I went to hook up my load bank in 3 phase to do a load check and had no power on L2 nor would the % of load meter work. I took the side covers off and checked for loose or missing wires,all was good. I then put the gen in 120/240 mode and had current to L1,2,and 3. I rotated the voltage switch multiple times it snaps into each position fine. I thought maybe the arrow knob on the switch was reversed but found out that it is indexed and only goes on one way. So 208 3ph is where 120/240 single phase is and vise versa. The question is, can this be fixed by changing some wires easily or should I just remark the knob and leave it alone?

It sounds to me like someone wired the switch wrong, you may want to check the TM for connection numbering and compare to the switch. I know on the the MEP-002a there were at least 2 different version of the switch installed with different wiring connections on each (2 are covered in the TM, but there may be a newer replacement also, this is the situation with the starter on the MEP-002a there are 2 starters listed in the manual, and mine has 3rd newer style, I say newer as it has a web address on the label), not sure about the MEP-003a though.

you can take the switch apart and reverse it-probably what has happened. i had a switch not working and tooke it apart to fix it . mine now works but is also reversed. left mine alone as i'm a firm believer in" if it ain't broke don't fix it"
