Voltage issue

[wally426ci]

Yesterday i lost the fuel and temp gauge. I converted to volt gauge and it randomly dips from 13 to about 11 volts.

I didn't listen and neglected to run a gauge volt limiter. I will do that now and i assume i toasted the fuel gauge.

Any idea on what causes the volt spike or dip? Alt, coil, ballast? Exterior regulator is new Chrysler.

Shawn,
Did you put a new voltage limiter in your truck?

No but that will happen this week. Me cheeping out did not pay off...

I translated my first post to english.

Anyone have any ideas on what causes the volt issues to begin with? I have an ok idea of the current flow but not sure if this is a symptom of a coil problem or what....

Voltage limiter....
Seriously though, the limiter is integral to the fuel gauge. In many
circumstances, when your fuel and temperature gauges start to act
up, it is the factory voltage limiter beginning to fail. If the limiter
craps out completely, this opens up the chance of a full 12V passing
through your gauge cluster, as opposed the the normal "limited" 5V.
I would strongly suggest investigating this as a possible cause of
your problems, or keep a pack of Oscar Meyer Wieners handy for your
next wiring harness BBQ.

Funny guy.

I appreciate it. I'll dig into it soon hopefully.

The voltmeter sense line is connected to +12V switched power the run circuit and is independant of the gauge regulator. So I think your gauge regulator is bad as well as something with your charging system. First pass I would just get a parts store to test the system in the truck or the alternator on the stand may be better. I am not sure if they can also test the regulator.

BTW electrocuted hot dogs taste bad.

I had a comercial made setup to do this I think from a Boy Scout catalog in the 1970s and they had a strange taste.

Thanks Kurt. On the same day I could hear a brushing noise possibly from the alternator (which was rebuilt) so I will swap it out as well and see where we get......

I made a hot dog cooker from a couple of 18 or 20 penny nails bent at 90 degrees on a board with the wires connected to the nails(you're right, tasted nasty). I made an electrical motor once from scratch that ran on 3 volts....we hooked it up to my cousins GTO battery and it spun so fast, it flew apart.

Hows the red wire that goes to the ammeter from the connector I bet your losing some voltage there check the terminal on starter relay then check the red on the back of ammeter
