Help with Yamaha

[heatseeker]

Motor is a 1995 c85 that i rigged myself on my 17' center console. Motor would start fine without a problem. Last week while trying to crank it over all the power to the motor quit all of a sudden. No tilt trim either. After inspecting it, i found it to be the main fuse was blown so i replaced it. Now everytime i just turn the key to the on position without even cranking it the fuse blows and nothing works, but if i dont turn it to the on position the tilt trim works fine. I checked the wire harness and everything is fine, no kinks or cuts. Ive been told it could be a short but where would i likely find a short? The grounds are all fine too. I was also told that it could be the regulator rectifier but i thought that the rectifier was only to convert ac power to dc. Could it be giving out too much power therefore blowing the fuse? Any help is appreciated as i am all out of ideas.

Thanks,

Andres

"Typically" a bad ECM will cause the fuse to blow. I hope that is not the case.

Thanks for the quick reply.

This is a 2 stroke carbed motor. Isnt the ECM for electronic fuel injection?

Backtrack that main power lead leaving the motor. Especdially around the tilt/trim mechanism and coming thru the harness. Sounds like it's grounded....good luck!
