Gday everyone the names Jake im a apprentice mechanic worken for holden.

I have a 94 hyundai lantra. Long story short i was driving down the freeway and i notice my battery light and handbrake warning lights were lit. anyway ive notice no powerloss or any other problems soo far. but the problem is only intermittant the lights will only come on and stay if i shift over 3grand or do any speed over 60km's. but say im crusing around the streets short shifting and doing about 50km's no lights apear. can any give me a heads up on this situation? could it b a fuse or relay thats causing this problem or a short.

Any feedback will b appreciated thanks.

 

id say sounds like a short. Dosnt get bothered till the cars rpms are raised enough/ when the speed is high enought to vibrate it in to contact with a ground.

 

It could also be your altenator going out on you. Or the altenator belt might be loose. Check the altenator. The brushes might be worn out.
