92 xj 4.0 aw4.
today got in the jeep.
New yellowtop btw. (3months old)
voltage is around 12 volts.
usually at 13-14.
No lights were on.
or left on.
parked and turned right off.
check engine light.
figured oh whatever.maybe its a 12 and end of codes. because voltage low.
pulled out of complex.
at 14.5 as normal.
figured okay we good.
CEL stayed on.
10 mile drive to work.
stopped at work.
checked the codes.
41 only.
means alt field circuit.
got to work. car sat for 9 hours.
drove home.
same thing happened.
CEL still on
So.
Does this mean alt is shot ? or could it be something else.
I would like to note.
On sunday. (like 2 days ago)
I added some 8 gauge grounding straps from battery negative to ac compressor. and from bat negative to frame. also from frame to intake manifold.
Could the additional charge (my old grounds were pitiful at best) the stock ones torn off long ago. Have killed the alt.
Should I keep driving see if she acts more funny ? im a little worried will pin battery to 16+volts and fry my new yellowtop.
Input thoughts ideas ?
thanks.
