roninjiro Posted November 24, 2007 Share Posted November 24, 2007 i think i might have a screwed up MS2 3.0, and tossed my simulator from my previous MS years ago...... if anyone has one, im interested but not willing to pay an arm and a leg for it either.

woldson Posted November 25, 2007 Share Posted November 25, 2007 Could you give us a what the systoms were, and how you found the prob? Good job by the way! Quote Link to comment Share on other sites More sharing options...
roninjiro Posted November 25, 2007 Author Share Posted November 25, 2007 actually the problem wasn't the main power relay.... i also noticed that the fuel pump relay wasn't kicking in so right off i knew that the relays aren't the problem.. i tested the fuel pump relay wire coming from the MS system itself and turns out im getting 12.4 dcv there... so now the problem is indeed the actual MS board itself. upon further inspection, i have found that Q4 has two leads bridged together.....just buy looking at it is hard to see, but i ran a continutity test on it and sure enough unlike the other ZTX450 this one was certainly bridged... so i have to go over the entire board to make sure i didnt goof up anything else. any other ideas on why my board is sending 12vdc to my fuel pump relay output would be greatly appreciated btw i could still use a simulator if anyone is done with theirs....
