I have a small question. The volt gauge in my 91 suburban has started to
read low, about 12.8v. I have check the battery with a volt meter and see
14.2v w/ nothing on except for the engine running and 13.9v with all the
accessories running. So that tells me that the alt is ok and the gauge does
not correspond to the volts found at the battery. Has anybody seen one of
the volt gauges go bad and read low?
Could be a charging system prbblem. I sumrise the Dash guage reads low while in
Loose belt? If you installed a new alternator, does it have the proper pulley?
(they come in different sizes)
Could be lots of things, or could be nothing at all.
I don't think anything is wrong with the alt. The reading does not change
if in drive or park. It's a serp belt so it can't be loose and it is the
same alt. The gauge reads low but a digital volt meter on the battery reads
fine. So the dash gauge does not correspond to the real volt. The volts at
the battery correspond to the volt available from the lighter. So it is not
a body wiring problem. I'll have to check to see if LMC has a replacement
gauge and just replace it.
Thanks for your reply.
the gauges on thos trucks have problems... If you see more 13.9 with a
DVM at the battery with everything running then you alternator is
fine. I would say the gauge in the dash is screwed.
I've not been able to get my temp gauge to read anywhere near correct
since I"v had my 92 K1500 (bought used) many miles on it. I'm not
aware of any way to fix the gauge. I resorted to an aftermarket
alt and temp gauge (autometer) oil pressue and gas gauges seem to
work fine. Not much you can do on those things except maybe swap out
the cluster if you were able to find a "good" one in a junk yard.
so you take the cluster apart and replace these ...where do you get
Cluster comes out rather easy.... I've never taken the main part of
the cluster apart...it did not look like the cluster had
I'm assuming you are talking about GM OEM Parts?
Follow on to my own msg.
I'm looking at the current LMC Truck catalog (winter 05)
CD-5 for 1/2 and 3/4 ton 1988 through 1998.
If anyone has this catalog or knows a GM part number or web
reference to "replaceable modules" for the dash cluster gauges
on a 1992 K 1500 Chey Truck I would be interested in looking at that.
I don't see anything like that in the LMC catalog. Additional info
would be appreciated.
Guess I'm wrong.... I assumed the suburban
was the same as the pickup on the dash?
If they are different then my mistake......

Yes, they often are a bit off from actual volts and do tend to get more
off over time and hours of use...they are a pretty low quality gauge. 2inch
gauges fit in the holes in the gauge faceplate if you wanted to go through
the task of installation. otherwise, you can just keep the knowledge of what
the actual volts are in relation to what the reading on the dash is.
