Ok this is going to be kinda long winded. If you wanna read the short version, scroll to the bottom.

I have a 92 SC400 for my daily driver, just small stuff done to her, cone filter (too lazy to do bfi), coilovers, wheels, and HIDS, so nothing major.

When I first got the car, I did the timing belt, water pump, and all that jazz, then my alternator went, so I just replaced that.

Now i'm having a starter issue, I've read about how to replace, and check the contacts and whatnot on the starter, but my issue is different.

I'm getting starter run on, at first it was random, I would drive and then it would do it, the car wouldn't run, everything would shut off. I went to inspect everything, and my negative battery cable was loose, I went ahead and tightened it and it went away for a few days.

As of today, I started driving her, and then bam starter run on. Shut the car off for a bit and it went away, drove it back to my shop, and it happened again.

So i'm trying to figure out what is going on. I turn the car back on, and it runs smooth as silk, turned the heater on, and BAM starter run on. I shut the car off and on, and switch the heater on and off, and everytime the heater was on, it would have starter run on.

After a few more tries, it went away, even turning the heater on and off, it would NOT have starter run on, I go gun it down the street, I turn around, and as i'm about to gun it again, I get starter run on, but for ONLY a quick SECOND, and it goes away.

I let the car sit all day (after going to austin for my niece's b-day), and I come to pick her up, and now every time I turn on the key, the starter automatically starts going, and it doesn't stop.

Here's the short version

Starter run on, goes away, comes back a few days later, sits for the entire day, try again and now the starter starts going with just the key in the 2nd position (after the ACC).

I'm wondering if anyone else has had this problem, I'm sure everyone is aware that the starter is ONE hell of a job. I'm also wondering if someone has the starter wiring diagram.

Thanks
 
Hey thanks for the quick response! But too bad you don't have anything listed for my problem...
 
sometimes when guys wire the STA circuit in conversions it backfeeds through this circuit but this would be unusual with a standard type car. I have had another car do this and it was the ignition switch itself that was stuffed. Cheers
 
Gloverman! It was as you said, the ignition was bad. My father came up with this conclusion also when I told him my issue. Thanks!
