Alternator jumps up and down

I noticed that the alt needle would go up and down with the fuel gauge needle(which has been working intermitently) when I would rev the engine the needle would go down, then go back up to 14vlts when idleing. Alternator problem?

Have alternator bench tested, could be the alt., test to confirm. Issue could also be bad wiring or faulty gauge cluster.

Why did this happen all of a sudden, Overheating (maybe) and RPM Sensor Pointing down?


If the noise was coming from the cooling system, first try to replace the radiator or expansion bottle pressure cap. The RPM needle probably is unrelate to the cooling system problem.

Bad battery or alternator


check alt fuse, check from alt positive post to battery make sure you have 14 at alt and close at battery also if you ran battery down a few times may need to be checked and or charged that and dont be fooled some alternators that are rebuilt just had a little part here or there replaced ya might have got a bad one

My 2005 chrysler town and country wont start. it just makes a clicking noise as the gauge needles max out before returning to zero, the dash lights and radio still come on. what could be the problem?


it mite sound weird but your alternator mite be the prob like the diode on it can be out and it will make your car not start that is why your gauge jump like that so next time your gauge's jump as you try to start it but it just clicks it mite be the alt. hope this will help people out there.

2001 chevy silverado 4.8 gas gauge not working properly


Fairly common problem with GM vehicles. The sending unit in your tank has a small circuit board that an arm is attached to which moves up and down according to your fuel level. This circuit board and arm are not making good contact. Unfortunately the only good solution is to replace this part.

Ford f150 pickup not charging


the gauge is going bad or a bad connection to the gauge! a sure way to find out is put a meter on the alt. and the battery when the gauge reads low and see what the actual volts are and if there high 13's and low 14vdc then you know the alt. is doing it's job and the gauge is bad! good luck
