V3.0 board does not power up
Posted: Mon Aug 02, 2010 7:09 pm
OK, I have a V 3.0 MS1 that I haven't used in some time. I replaced it with an MS2 complete kit when it died. Well, now I want to squirt my riding lawn mower, (no I don't have too much time on my hands, and why does everyone keep asking that!?), and want to fix it.
When I hook up the stim, I get nothing. I pulled the CPU, and tested for voltage and got between .92 and 3.8 on pins 1, 12-15, 18, 20-28, and 31. I also notice that D19 gets REALLY hot. I checked it, (D19), with an ohm meter and I have continuity both ways, (166 and 144). So I am thinking the first thing to di is replace D19. I am just wondering if any of you have any other ideas.
Thaks!
