The slave cylinder in the hydraulic clutch system of my truck recently failed and I took it to a shop and had the entire clutch set replaced. When I went to go pickup the truck, the battery light was on. They tested it and it wasn’t charging. Smoke was pouring out of the alternator so they replac…

The truck was used quite a lot last weekend and never skipped a beat so I am hopeful this is solved for a while.

Something else came to mind if this problem returns. Someone mentioned a neutral safety switch. This is a manual so doesn’t have a neutral safety switch but does have a CLUTCH safety switch. I wonder if that could be the issue. Keep in mind that this started right after the clutch and the two as…

I had an intermittent no-crank problem w/my Corolla one time traced to an “iffy” clutch safety switch. Temporarily bypass isolated the problem.

Interesting… This all clicked for me when someone mentioned a neutral safety switch. Did you get random clicks like with a dead battery but when it decided to fire, it fired with great gusto like the battery was perfect? I am going to figure out how to bypass this but leave it intact until it hap…

Sounds like this my next target if the problem returns…

As I recall the circuit design involving that part on my Corolla is weird. They changed the arrangement prior to my model year, then they changed it again the next year, so apparently they were trying to come up with a more robust method. If you post a schematic as it applies to your truck you mi…

I will get on this in the next day or so. It appears I have several pins on the assembly so it isn’t just two pins to complete a circuit.

As a DIYer, I learned years ago to go back and check my recent work when something fails. There are coincidences but not as many as we think.

Testing the inputs and outputs of a remote mounted starter solenoid is basic electrical diagnostics, even an IT man should be capable of this.

What could a mechanic do to fry both an alternator and starter?

See ok4450 stumped to this point. Very very long and frustrating.
