Bad ground? Please help!

Asked by Nov 13, 2015 at 03:05 PM about the 1993 Chevrolet C/K 1500 Cheyenne Extended Cab LB

Question type: Maintenance & Repair

I have a 93 Chevy Silverado 1500
4x4 ext cab, short box with the 5.7l
motor n auto tranny. My problem is
this, since I had my motor replaced I
have had weird electrical things
going on. Such as when I turn my
turn signals on, my radio cuts out for
a second, my speedometer and tach
dance when they blink, and my
battery gauge drops. The battery
gauge never reads at 14, maybe at
10. I can't use my headlights, and
radio at the same time, I can't use
my windshield wipers and radio at
the same time. It's almost like there
is not enough power. But my truck
starts and runs just fine tho. Every
time I hit the brake or anything that
uses power i can see all the gauges
react. Even my fuel gauge. Any
ideas??? I can't take the truck back
to where the motor was done as that
shop would only charge me a arm
and leg. They bent me over for the
motor replacement when I supplied
the rebuilt motor to put in it.

Did you check and make sure all the ground straps were re- installed? Check and clean your battery terminals and cable ends and have the alternator checked too.

I'm not sure when Chevy began using ECU's but you may find this usefull if you have one ... ECU's utilize isolated grounds for data so be aware that there are conditions when the ground is controlled rather than +12. ... I know that O2 sensors use a controlled ground in able to sense the heater current as an example. Notice at the bottom they reference the ground distribution schematics

I just looked at my motor and it did not have any grounds. Is there 1 to the engine block to firewall and 1 from the battery to the frame?
