Wiring / jumping the starter, To turn engine over Options

[Hammy]

I've searched but can't find exactly what I'm looking for.

I have a motor (still in the car) that I'm trying to test compression on before I remove it. I have most of the FI/engine wiring harness disconnected so I'm wondering if I can wire up leads from a battery to the starter/solenoid so I can crank the engine over? Is there an easy way to do this?

You need to hook up the battery, ground and positive.
Large positive goes to large terminal on the starter.
Ground could go on the lower bolt of the starter, or just make sure the normal tranny strap is in place.

Make up a 30 am starter push button switch and connect on end to the positive terminal of the battery, and the other end is a femal spade bit on the starter solenoid.

Press button...off you go.

For rapid action, take a screw driver and touch the larger terminal on the starter to the male spade bit on the starter...same results.

If
Ed was there, he would show you a quarter fits between the spade terminal and the larger on on the starter, same results.


Now, your compression test will not really show you much with the engine cold, in fact your results will be worse, so until the rings best up and expand....your compression will suck.
