Pulled out the tester...
So I finally got some decent weather again, and decided to pull out the multimeter and look at some stuff on my impala.
I followed the procedures that Danthurs put up on the how to section, and tested ignition coil posts and the battery posts to test the charging system. I took a brief look, because I didn't want to do anything that could cause any problems since I don't want to get caught with having to fix something before the school week begins again (yes I'm sorta obsessively cautious, and I was unsupervised so I didn't want to pull too much apart).
Heres what I got
The coil for 4 and 1 had a resistance of 5.85 ohms and 6 and 3 had a resistance of 5.83. I would've tested the 5 and 2 but I was a bit worried about the state of the wires as well I have no di electric grease at the moment to touch them back up (will have to do that tomorrow). They look to be in bad shape. the ends are breaking apart and on top the they are looking worn, I was afraid that if I gave the wrong one too much force while pulling, id break one, so I left the two in the middle alone.
I did some testing with the battery posts as well. Heres what I got.
Car off: 12.6 volts
Car on, at idle: A wide variety of voltages, 14.7, 5.0, 8.0, 18.3, 3.7
The voltage was constantly changing, and it happened along with the contant shudder of the engine. If you guys don't understand what I'm saying, I'll gladly put up a vid if you guys prefer. Otherwise, you guys have any ideas?
