What gauge wire are you using? 0/1?

Are you sure the spot you chose to ground the battery is a good ground?

Do you still have a ground wire running from the battery to the engine block?

i was using 4 guage power wire....

purdy sure it was because some times it would start it would crank for a lil bit then start and some times it would crank and not start at all...

and yes...

94maro

also had a seperate wire form the altintor back to the battey to charge it, and that was way smaller guage wire...

I don't think 4 gauge wire is large enough.

my freind has four gauge wire in his mostang and his works...i also put on my smaller alternator pully so it will spin faster and that didnt do nothing..lol

Well get a hold of a digital voltmeter and test the power output and grounds when you are having starting issues. Also test the power output from the alt while the car is running.

My trunk mounted battery cables are zero gauge - as 4 gauge is far too small.

Also, route your Neg cable all the way back to your block as well; a frame ground will not cut it.

What size.. that may be your problem.

Grounds are your friend with this.. I have 2 ground points off of the Neg Terminal in the back, and I have 2 coming off of the Engine aswell, one is the stock strap, the other is some 6ga Wire from the Block to the Frame Rail.

As far as the + side, I have 4ga Welders Cable going from the Battery to the Distro Block, and from there it goes to the Starter and the Alternator. I haven't had any starting or voltage problems.


Here's some pics of mine..

Battery mounted and grounded to the Body (I don't have that braded Strap, that was for testing. I have a 2ga Cable in that place for that)


Jumper from the Body to the Frame Rail


4ga connecting into the Distro Block, one going to the Starter, the other going to the Alternator


You can't see where it is on the Block to the Fram Rail..it's from the Motor Mount Bolt to where the stock Heater Core Lines bolt to(I got rid of them), it's a cable about 12" long.

you will need to add a larger gauge wire for the battery and add atleast 3 more ground straps to the body/frame so you will always have better groundage for the body and better charging.

If he had 4ga Welders Cable then it would be a different story, that stuff conducts exremely well, and is very light weight for the purpose it's serving.
I do agree more grounds are best. Like I mentioned I have 4, and mine works very well, voltage doesn't drop past 13.

yea, def. some better cable needed.

i used 1 gauge welders cable and haven't had any problems.

put the stock alternator puller back on too

A little Fluid Film will protect the terminals for at least 12 months. If you haven't tried it yet and live in the USA, just PM me with your contact info.

Those grounds are important! I have one coming from the battery to the right side frame rail then a braided ground strap from the engine block to the kmember...then another one by the radiator support to the engine. Mine engine cranks normal.

Power 4ga wire is not large enough for the distance it has to go. 0ga is ultimately the best(welders cable) you simply cannot get better than that!
Ground 4ga is sufficient however your grounding point(s) must be good i.e
battery to solid frame area such as MERV shows,frame to engine block,block to k-member is the BEST way to have your driver grounded, hell from the factory EFI cars have not had sufficient grounds!

94maro

ok so better power wire and better grounds..lol

o and why put my stock alternator pully back on??

you are experiencing charging issues, eliminate all other possibilities first before you end up drawing the wrong conclusions. definitely upgrade your wiring though. once everything is straightened out and you wanna slap the pulley back on, thats your thing.

94maro

i had the smaller pully form my march pully set i had purchased a while back and never installed the pully part but no i have..lol

94maro

ok so ground the negative from the battery to the block? or the frame? or just a good spot in the back? and what else needs to be grounded? the alternator is already grounded i beleive by the bracket holding it right? o and pictures help alot =] thanks...
