Alternator Test Quick Question

Hey everyone,

I have a quick question, I know on gasoline powered cars that if you disconnect the battery and the engine/electrics die then the alternator is bad.

I dont see why this test wouldnt carry over to the diesel powered cars as well..minus the engine dieing (for obvious reasons)..but you never know.. I am just wondering.

I have my dad's SD here and I checked voltage at the battery, it was 13.6 when the car was running. We put on the headlamps, blower and a few other things and I disconnected the battery...everything turned off (minus the engine). I checked voltage across the disconnected battery terminal and ground..got nothing. I also tested the dist. block on the rail..got nothing.

Safe to say dead alt? correct?

Just thought I'd double check this with everyone...


Also: how is changing the alternator on a 126 617 compared to a 201 103? I've done the 201 a few times. Its a pain in the ass. I'd think the 617 is easier due to the belts and what not

Thanks,

Kris
