zane9000 Posted March 26, 2006 Share Posted March 26, 2006 So I tried to power up my MS today so I could load the code and start tuning. Turned the ignition key and the relays clicked. Joy. Started up my computer and went to test it with hyberterminal. No connection... Trouble shoot for 10 minutes in computer... Trouble shoot the MS wiring for another 10 minutes... Then check the fuses. A fuse was blow. wooters for hooters.. Put in another fuse, turned the key, pop.... I see a day of rewiring ahead of me soon.. Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted March 26, 2006 Share Posted March 26, 2006 Welcome to DIY... no wait, welcome to working on any electronics (be it SDS, FAST/BS3, etc)... this stuff is bound to happen either way. Just be glad parts are cheap this way! And better be happy for fuses too! So which fuse did blow? Quote Link to comment Share on other sites More sharing options...
zane9000 Posted March 26, 2006 Author Share Posted March 26, 2006 it looks like the switched power to the main board (pin 37) is drawing WAY too much current... I may have a solder bridge or somthing i guess... I will troubleshoot it tomorrow or the next day.... Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted March 26, 2006 Share Posted March 26, 2006 Sounds like it. Quote Link to comment Share on other sites More sharing options...
Nismo280zEd Posted April 1, 2006 Share Posted April 1, 2006 this is why you use fuses... they are cheaper to replace than an MS computer. -Ed Quote Link to comment Share on other sites More sharing options...

wheelman Posted April 1, 2006 Share Posted April 1, 2006 Did you assemble it? Did you use a stim while assembling to ensure the different circuits were good? If you don't have a stim I'd invest in one, it will make the trouble shooting much easier as you can do it at the bench and send the tach, temp and MAP signals to the MS without having to wire it to the car. What version of MS are you working with? PCB, CPU and code? If it's a version 3 PCB, did you install the flyback circuits? I got one of the diodes in backwards and had huge current draw.
