I have a 95 civic coupe that will not have any power when the key is to the on position. I just replaced the alternator and battery. When the key is on there is no power so I need to jump it and when running it will not charge the battery. Any ideas on what could be wrong? The car is not throwing a cel.

I would suggest you check your main grounds first regardless.

Does anyone have pics of the main grounds? Sorry I'm new to the civics

Do the headlights and hazard lights work?

EgCouped15b

Yeah they do

Does the starter crank the engine when key is held in ON(III)?

EgCouped15b

No nothing happens no lights pop on no crank no fuel pump no nothing like the battery isn't connected but it is with brand new terminals

Former User

Give more details about this^

Because it suggests that your new battery is dead.

I jump it so the alternator can charge the battery but it does not charge. Have had my battery and alternator tested and still nothing. Can it be a bad ground for the ecu?

Former User

When you jump the battery, the engine starts and runs, right?

When you disconnect the jumper cables with the engine running, does the engine stall or keep running?

EgCouped15b

It still runs like a champ after the jumper cables are off

1) Have the new battery tested. Charge/replace if necessary.

2) When the engine is idling with all accessories off and jumpers disconnected, what voltage do you read across the 2 battery posts?

I have found out my problem. It was a bad ecu ground runs like a champ now! Thanks for everyone's help
