I just bought this truck a month ago and have another annoying
If I let my truck (1996 Yukon w/350) sit for the weekend, the battery will
be almost dead when I try and start it on Monday.
I tried to check the amperage at the negative battery cable but got very
negligible readings. I.e.. with the Multimeter on 200 MicroAmps I get a
reading of .2 I don't see how this little of a draw can be affecting the
Since I just bought the truck I went ahead and bought a new battery today,
so I know for sure that isn't the problem.
I checked again with my multimeter this afternoon for the amperage draw and
with the meter on 200 MicroAmps it now reads 1.1.
While watching the meter I went ahead and started pulling fuses to see if it
would go to zero and isolate a possible problem.
I pulled every fuse in the panel on the end of the dash and there were no
I went under the hood and pulled all those fuses and there was still no
I connected the battery and tightened all the connectors and started the
truck to measure the alternator output.
With nothing on the Voltmeter rear 14.1 VDC.
When I turned the defrost on full, brights, and rear defrost on, the
readings dropped steadily to around 13.4 at idle
Are these reading too low?? Since the alternator is directly connected to
the battery is there a possibility it is drawing current??
On a side note, I found the original window sticker for my truck and it said
it has daytime running lights.
I noticed the little green light on the dash, but I have no extra lights lit
when I start the truck.
When I did my load test I noticed on the two inside brights were lit. Is
this normal, or is a filament on my outer bulbs burned out??
Thanks again for any help,
