Loose wiring, bad ground, or fusible link is my first impression. Make, model, year of vehicle would help.

It sounds like you may have a bad voltage regulator. On some models the voltage regulator is inside the alternator so it may be bad. Normally when you turn the AC on there is a circuit that brings the engine idle up a bit to compensate for the load of the compressor, that too may be malfunctioning. Did you look up your vehicle on the internet to see if this is an issue with that particular model?

Gauges move when stopped


Sounds like it could have a weak alternator. In gear the idle is always lower than in park. A low voltage situation could cause the gagues to act up

95 montero transmission shift problems + overheating + battery not charging


The first step is to see if the gauge are correct,low voltage can cause many problems, the first step is to make sure the coolant is full so check radiator, this is done when cold, if full then start the engine with a meter on the battery and watch the voltage, have someone put it into drive while holding brake. if voltage on meter starts to drop then give a little gas to rev engine and see if voltage goes up, if it does then you may have to low an idle but if the idle is ok then alternator is bad. also have the battery tested to make sure its good, just because it starts the truck does not mean its good. the next thing is to look at the overheating problem. if the cooling system is full and it runs hot then that must be looked at,when the truck is starting to overheat we assume it is due to gauge, but this sounds like it may be low coolant or low voltage or idle is to low because when you put it in park it drops. start with these checks and let me know the results. good day.

No. It is a bad alternator. When they test the alternator they turn it at faster rpm. When it turns at faster rpm it is charging fine. What the problem is the voltage regulator in the alternator is going bad. When you turn your blinker on I bet the voltage shows on the gauge. Moves up and down with the blinker.

Battery lights is on & don't idle correctly


These trucks have what is called a smart charge system. It normal for the alternator light to elluminate when the truck requires no charging or the idle is low. The most likely reason you have low idle is throtttle body coking which requires cleaning or a bad idle air control valve. Also clogged injectors will cause a low rough idle but if that was the case misfires would show up and can be seen while they happen using a diagnostic data scanner.
And the first thing we always look at is the air cleaner. If you have a K/N filter the oil can contaminate the MAF senor. If the sensor cannot see and feel the air then it won't be able to add fuel causing a low idle, The MAF can be sprayed with brake cleaner to clean it. Usually you will get a p0171 and or a p0174 if the maf was causing a lean condition.

Very low idle will cause a very low voltage output from alternator, so nothing unusual about that. At low idle the truck is basically drawing from the battery, not the alternator. As soon as you cure the idle problem, the alternator gauge reading will return to normal.
