Battery light comes on/off 94 accord

[Hondina]

Hey there people just got a small question have a 94 accord and the battery light keeps coming on and off which in turn then affects everything in the car such as lights dim and aircon loses power etc.... ive checked all the terminals and stuff so was just curious if anyone had any other possibilities,

cheers

try changing the battery...?

[Hondina]

hey no i havent tried changing the battery it is a couple yrs old maybe 3, there was some build up on the terminals which i cleaned off, so i will get a new battery and see if that fixes it.

mate, take it to supercheap, autobarn or repco and have them test ur battery for a dead cell.
always the best place to begin, its free to test too.

[Hondina]

Ok cool yeh will get them to test it, was curious aswell if it could be a faulty alternator? so it keeps dropping off the charge

[FAT VTI]

could be 1 of many things, however start with the source of power= battery, easiest to test & to replace :D

[Hondina]

ok yeh will do have had a chance to get it checked but its weekend so yeh will do it this weekend

I reckon it is your alternator. Especially if you are driving at 2000-3000rpm and you still get the battery light flashing.

[Hondina]

is there a way of getting the altenator tested?

Measure the voltage at the battery terminals using a multimeter when the engine is running. It should read 14V. If it is 12V or lower, then your alternator is dying.
