Power everywhere but the gauges and now won't start.was running put in reverse and it died ?checked the fuses and now lost help

Did you check the main fuse under the seat near the battery?

Dangerous practice to try & jump a near dead battery

Always try charging a battery, that is only a couple years
old & not run down more than two or three times

If the battery is dead & reads less than 12 volts, have a parts
store test it or just replace it.

Jumping a cars battery is not a fix for anything,so I fail to
see how your lost & have not addressed the battery issue,
so you can continue on with other testing,if needed

Your bad cable may have prevented the battery from being charged up good. Put a battery charger on it, or replace it if over 4 years old.

So the problem is it starts and then dies? How many amps did the alternator show? Was it enough to run all power circuits and charge the battery as well? That could be a concern. It is possible you have a bad ignition switch, but first check the fuse for the gauges in the instrument panel fuse block-it may be labeled "gauges" or "meter". The fuse should get power with key on, and then power is sent to the gauges on the dash. Without a voltmeter to test for power coming out of the switch, it's kind of a guessing game. If power is not getting to the gauges, it may also not be going elsewhere out of the switch.

Any issue with a security or theft alarm light staying on? That would disable the engine from running. Post back with year, make, model, and engine size. Maybe I could look at a wiring diagram for further help.

It looks like you have a short somewhere. You would need to inspect all the wiring related to that in order to pin point the problem. Also check if there is another system working from that same fuse. ie. Power Outlets. Sometimes if they go bad it will blow the fuses shutting down everything else.
I hope this helps!

have you check the fuel pump relays and your imobliser if you have one

you need to check the voltage at the battery when you have trouble. should always remain above 12 volts.
If not then the battery or the connections are bad. first test the battery right at it's lug terminals, then check the terminal connectors. battery or cable or connectors - def sounds like major voltage issue in the battery area!

The stall in reverse is most likely unrelated to your problem, unless your alternator went bad, and your battery is discharged. Try charging/replacing your battery. A jump start may not work as Dodge trucks don't like to idle well with a weak battery. Then try starting again, if it runs check the voltage at the battery. You should have 13-14.5 volts, if not you have a dead alternator. If it still won't start, please post some more details.

may be a fuse or coil check for spark had simaler prob with a jeep ended up being a fuse for somthing completly differend but they run in same sercut

Have you checked your injector pulse? Also check your fuses. What engine does it have?

Most likely the alternator........ map sensor failure would bring up a check engine light and code not the crazy gauges and lights
hope this helps...Good Luck!
