MS LED always on with ignition off
 
I just installed my standalone MS but It wouldnt start sadly.

I plugged it in and LED's 1 and 3 were always on. I have installed the IAC mod and fan mod. I have the msq loaded from the 90-93 PNP and followed brainecks write up other than stuff the megamanual said to do for stand alone.

Any ideas what's wrong here? I couldnt find anything about the LED's being on always which makes me assume my problem is unique :mad:

please help

thanks

hm... wiring issue?

91NApeewee 03-15-2008 04:27 AM

thats what i thought, but i checked it against braineck's wiring pinouts and i didnt notice anything.

Sounds like you have it hooked up to 12v, not the switched 12v. Double check ti against the madracki diagrams.

I figured it out last night at 5am. Switched up a stupid wire, that is what i get for building a harness at 4am during finals week. It fired right up now.

Is there any place I can find what outputs correspond to which db37 wire? (ie. JS0 goes to....)

kinda, but what do they correspond to on the harness? Like If i have output 1 as my fan trigger, what db37 wire is that so i can hook it up to the car harness and power the fan.?

They aren't connected to a pin on the DB37 harness. That is why you either have to jumper them or build the appropriate circuit for that input and then connect it to an available IAC1a,2a,1b,2b or SPR1-4 pin. IAC outputs are 25,27,29,31, SPR are 3-6.
