Fan Mod Help
I have a 91, with a DIY standalone megasquirt. Everything runs great, except megasquirt seems to have no control over the cooling fan. The stock thermoswitch works them fine.
I followed the directions here: Common MegaSquirt Modifications But I connected it to js0. I have js0 set to fan control in megatune, and the indicator in megatune comes on at the correct temp. The fan doesn't physically come on. I have 1A hooked to pin3 on the D37. Any ideas as to what to check? Thanks -Rouphis |
So you put the output on Spare 1 (pin3), but 1A is not the correct spot on the harness, try 1R!
|
I'm sorry, the letters on the diagram are kinda hard to read. It is on 1R, near the clutch switch wire.
|
I did some probing, and if i short pins 2 & 3 the fans come on. but its a no go with the MS doing it. So the issue has to be in my MS
|
then the transistor is not switching, did you reverse the gate and emitter?
|
Nope, the Transistor was doa. I replaced it with one from radioshack. In the process of changing them out, I damaged a thru hole in the proto area. The via came out with the npn. Thankfully it was on the B not the gate or the emiter. All is well now.
Thank You for wasting your time on an unworthy n00b like myself -Rouphis |
