i had on my dome light in my car since friday and i didnt know until sunday night because i didnt bother to go out saturday because there was a sno storm. anyway, i got a boost for about a half hour the car will try to rev up but its not catching at all i dont think its not the battery because the healights go on stereo works n none of the interior instrumnts (dome light, stereo speedometer) are dim. Also my compustar car starter isnt even working either it does the same thing plz help

 

car would rev up but not catch ? explain ...

You need to drive around for couple of hours upon jump , reason why lights are still dim ... car needs a load on it

 

I don't know how to explain it anymore

 

Try to do a complete reset on everything. Unplug the battery negative terminal for 15minutes and then reconnect it. See if the car operates normally afterwards.

 

I just got a read out its a communication error malfuction number 2

 

Try a new battery. If I understood you correctly, you have the battery hooked up to another car for a jump, but the car will not turn over? If this is the case you need a new battery. Your car is running off the power of the other car and that is not enough juice to bump the starter. Other idea is to put that battery into your car, start it, and they transfer yours back into the car to be charged by the alternator.

 

No don't do no battery transfer it's not a 1970 pick up truck, not only will this not work, but you can damage electrical items.
