compression test

[jonathan]

i just ot a a cheap diesel compression tester from harbor freight i have a dumb question how do i use it lol boy isnt a dumb one

 

[jcarr]

best way is to screw an adapter into the glow plug hole with all glowplugs remove and crank engine at least 4 rev's. do this for each cylinder.

I found the US GENERAL tester from HF didn't have a glow plug adapter that would work.

I had to use the Injector hole adapter.

Make sure your batteries are fully charged before doing a compression test. You'll need it!
