no start after battery relocation

[matta]

I think im getting a bad ground. I have the negative grounded on one of the little studs on the rear tail panel, I sanded to bare metal though. anyone else have any ideas why I wont start. When I turn the key to ON, it all sounds like it did before the battery relocation, just when I go to crank it, it will be a faint whine...

good places to run my ground will also help me, so speak up!

thanks

Make sure the trunk ground is in a place with a fair amount of metal. ALSO you need a chassis to block ground up front. Engine bay battery - cables go from batt to chassis to block. Without the chassis to block ground the starter may not work or it may ground itself through the driveline. I know on starions without the chassis to block ground it usually tries to ground through the throttle cable and destroys it.

would not having a chassis to block ground cause a no start though, im just trying to get some cranking in before I tie everything down. the main negative ground is all i have going to that little stud on the rear tail panel, thinking thats the cause of the no start

Your starter grounds through the bell housing and the factory ground is on one of the Bell housing to block bolts, so it could. You can ground your battery to the trunk pan on one of the frame rail bolts.

Check out where Eric (turbosax) grounded his battery. http://www.dsmtuners.com/forums/han...-relocation-project-log-15.html#post151963035

I would move the trunk ground to a better location and make sure there is a chassis to block ground. Then the starter should work.

Take it from me: You have to ground everything. Overkill is key. Make sure the block is grounded well. Ground the IM. I havent done it yet, but i strongly suggest 4ga wire from the alternator to your positive busbar(or whatever the strip is called) up front. I grounded in the rear trunk as well as a 4ga wire all the way to the block and from the block to the firewall. Now if i had just not cheaped out and bought 0 or 2 wire i would have needed far less wire than i have. I had to run 2 4 ga wires for positive all the way from the trunk up front.

Complete overhaul coming soon. Wont make the same mistake twice. Voltage drop sucks too, thats why i recommend upgrading alt wire.

Agreed, run a dedicated ground to the engine block directly from the battery.

It fired up! anyone want to take a guess at what it was?

Tripped circuit breaker or fuse?

I haven't installed the 150A inline fuse yet. It was the engine to body ground. didnt think that would cause a no-start, but guess it did!
