I just installed a new 6G in my Foxbody(91) and it is not charging the Battery. While running I remove the positive cable and it dies immediately. I tested voltage its only at 11.51.

I use the yellow wire and the green with red stripe on the plug. Then use the 2 Black with orange stripe wires on the post as well as a 4 gauge off the post straight to the battery. I did everything correctly but it is not charging.

Has anybody had this problem or know what is happening that can help.

Thanks in advance,

Scott

so you used the correct stator plug, and cut out the spade connector? did you use an inline fuse on the 4 gauge?

do you have an underdrive pulley on this alt. if so that could be your problem. my 140 amp powermaster had a certain rpm it had to run in order to get maximum output, i think 2400 (alt rpms that is) and with a 3:1 pulley ration that is 800 engine rpms.i first put a bigger pulley on andhad the same results you are having.i put the stock pulley back on and it was ok. i also bumped my idle up a hair to about 850-900 not sure if this was the right thing to do but it worked for me.

I did eliminate the spade connector. I do not have a inlinefuse on the 4 gauge(what size fuse should I use?)

I do not believe there is a UD pulley on it. I do believe there is a UD pulley on the crank/fan though.

Also I was wondering if I should run an additional ground from the block to the frame?

Thanks
