battery relocation problem..

[6literEat'r]

ive relocated my battery to the trunk of my trans am, and now it cranks slowly, but will start, and everytime i shut the car down i loose my trip odometer.

battery is good..worked fine before this relocation..ive got it grounded to the rear seatbelt bolt and scraped the paint off for a good ground.the ground in the engine bay has a 0 gauge wire going from the engine block to the neg terminal that would hook to the battery, and them 2 are bolted down to a nut i welded to the body of the car under the hood.

positive cable is a 2 gauge cable i even used on my last car for the same deal, and had no problems with it. i ran it to under the hood and bolted it to the exising pos. terminal that bolts to the battery.

question of the day is....why is it cranking slow, and why is the trip resetting? :\

thanks in advance!

use a chassis ground. bust out the voltmeter and check voltage drop. voltage drop tests are your friend

could be a bad ground or bad wire. digital multi meter or volt meter will be your friend. like said before test voltage drop and continuity on ground

really think a chassis ground will make that much of a differnece compared to the seatbelt bolt?

Trip resetting is due to low voltage. My power wire was loose and it was doing the same thing. The cranking is probibly due to the strength of the battery vs how far from it the starter is. You might need to invest in a higher cca battery to get it back to normal. My grand am and mustang were grounded on a seatbelt bolt with no issues.

Yes. You will hear people say "most electrical problems can be blamed on bad grounds". This is very true.

Voltage drop across a long run can be killer as well. Like mentioned. The style of wire in the cable can make a difference with that too.

YES!! make a real ground

well..came to the conclusion that my power wire is too small..

went to lowes and got 18 feet of 1/0 awg wire...should power this fucker right up now
