Could be or the negative cable from the battery which runs to the ground at the fender is poor and then the cable after passing through this ground point continues on to the starter and that might be going to the wrong connection as it should be going to the long mounting bolt of the starter.

mofeel 10-04-13 10:29 AM

well i have the starter hooked up properly. the ground is going to the bolt that doesnt have the wire connected to it.

Pic of the starter in the link at post #40. This pic illustrates an incorrect starter so take this into account. Notice the triangular flange of the starter which has the hole through it? This is where the ground wire goes. And read the next post, post #41 as well.

You must have two, both are from the battery. The one w/the Yellow stripe is the ground and goes to the triangular part which mounts the starter to the transmission. This is how the circuit is grounded to the car. The other cable is the positive wire from the battery.

mofeel 10-04-13 01:08 PM

yea i messed up. i have the ground going to the post on the starter. thats my problem. i have 2 wires but ones the thick black and yellow and the other is the small power wire.

mofeel 10-04-13 01:13 PM

But how would the car stilll be starting up if i got it wired incorrectly?

The more important aspect should be if you don't have it wired properly then how do you go about in rectifying the situation as opposed to anything else because under the current scenario your car is not operating properly. As already stated, the negative ground cable off of the battery runs to a grounding block at the driver's side fender. Additionally, the starter grounds to the transmission housing.

mofeel 10-04-13 01:38 PM

Im so confused, and cant find a picture of one hooked up the correct way either.

satch 10-04-13 01:55 PM

All you have to do is read post #41 in the link provided and that's all you need to know and nothing else. Nothing.

mofeel 10-04-13 04:17 PM

I have 3 wires. Two are skinny. One of em has the connector for the starter. Other has a eyelet eith a black box on it. The large wire is all black and is a positive wire. So is the skinny wire with the black box a ground?

Like in post #1, first pic?

If so then it is a condenser and is not starter related. For the umpteenth time, the negative ground wire goes from the battery to the driver's side fender grounding block and then on to the starter's mounting spot. You need to follow this cable down frrom the battery to the grounding block and then down to the starter. I mean we're talking about a whole five feet or so of wire. You need to figure it out for yourself.

mofeel 10-04-13 05:52 PM

Yupp that one. The eyelet just broke tho. It was a signal wire tho.

mofeel 10-04-13 06:06 PM

I've followed it. It just goes to the trans.

misterstyx69 10-04-13 06:13 PM

The battery cable is like Rope size.
that little wire with the black chunk of hash on it is spaghetti size and has Zilch to do with the starting system.

If you look at the pic once again for the starter it has a triangular portion at the end of it in which the long mounting bolt goes through it. This is where the ground goes. It does not go to any other spot. The starter mounts to the transmission so the ground gets sandwiched between the two.

EDIT: And have you examined the negative battery clamp you recently installed? It should be soldered to the cable. Make sure it is up to square.

The eyelet chip thingy is for the Oil Sender and is normally bolted to the slave cylinder but the wire itself should not be grounded to anything or the oil gauge will say "I'm not working any more." Just tape it off as it is rather useless.

mofeel 10-04-13 07:07 PM

Well I added a 6 gauge wire from the battery to the mounting spot and it helps but I'm still getting a draw. Ill searchmore ttomorrow for the wire.

satch 10-04-13 07:23 PM

And in the process clean up the grounding block at the fender and redo the terminal clamp at the battery (both of them).

mofeel 10-04-13 07:36 PM

Ill do that as well. I also swapped the toggle out and just hooked the signal wire back together and jumped the bypass connector. Running at 12 volts. All accessories off. 11 volts with accessories on. Battery was still being charged by the alternator I assume. But when I cut the power I couldn't start it back up without a jump.
