420A No power

[Jonnychance]

The last few weeks my car (98 Eclipse GS stock) has had the battery light on Intermittently. It finally died last week when I got home.

I hooked up the jump pack and tried jumping it, it lost all power immediately. I figured it was the alternator so I changed it but it's still doing it. I've tested all the fuses and they're good, checked the grounds and wires to the starter. I got the battery tested it's good.

Also when I try to jump it the door jam light flickers on and off like crazy only when. The car door is closed not open.

Did you test the 120amp fuse (from the alt). Also when you get it running what is the voltage at the battery?

The one in the engine bay fuse box? I saw it this morning not sure how to test it, it won't even come out and before I swapped the alts was when I last had it running and it was at 13v I believe

Yes the one in the engine bay fuse box. If bad, your battery won't get charged even if your alt is good. Nominal voltage at the battery when engine running and alt properly charging should be around 14.4 volts.

That fuse bolts in. Examine closer.

Just read that.

The fuse is good. I have very little power in ACC position enough for my radio and once I turn the key to on position the power cuts out.

Fuse is good

You have bad battery connections, grounds or bad/discharged battery. For starters.

Had battery tested it's good. I've testing all the grounds I cld find and nothing g is draining the battery

Did you actually test the fuse, not just look at it? Either remove and check that there's continuity across it with a meter, or with still in place you can measure the voltage across it which should be zero if it's good (note there's still voltage from either side to ground however).

Yeah I unscrewed the bolts and tested for continuity

I would clean your terminals. Test the terminal itself (touch the center not the wire) to ground. There isn't much that can cause no power to the car.

Because of this, I'm betting the ignition switch has gone bad.

That's what I was thinking

They're cheap on RockAuto, but I would verify proper voltage at the switch before pulling the trigger.

Sounds good

I still need to verify but I couldn't find one on RockAuto do you have a link?

It's listed as "ignition starter switch" under subcategory "electrical switch and relay".

Why not bypass the switch and rule it out first?

I changed the switch and starter and it's still doing the single loud click at the starter. Before I swapped the starter I hit the old one and the car started, so I swapped starters but it's still doing it.
