Anyway to compression test a motor out of the car?
Anyway to compression test a motor out of the car?
I couldn't get ahold of a compression tester in time to test it and I only had the cherry picker for a couple hours. The engine, tranny, and starter are all still bolted together and this weekend I'm going to fill it up with oil and put on the oil cooler.
Could I just take some huge wire and run it directly from the battery to the starter to turn it over or is this a completly stupid idea? Which posts on the starter are negative and positive?

Make sure the trans is in neutral.
Negative, ground is the starter case itself.
If you're using a set of jumper cables (easiest), clamp the negative side onto the starter itself.
With the positive side of the jumper cables, touch either of the two terminal posts - only one will work.
Do NOT touch the engine or the starter case with the positive side jumper cable!
Can you say sparks?

Cool, I wanted to make sure I wasn't about to burn something up, thanks for the info.
