hey guys just bought a 87 legend coupe and i got a problem .....

ok when just botting around at about 50kph the car is fine but as soon as i get to 100kph the battery light comes on and when i turn my brights on the whole car dies jerks and bucks then goes normal ....I havent had a chance to trouble shoot yet ,but just looking for any advice maybe someone has had this problem before and might save me some time

i'm thinking its a bad ground but allso think it could be a relay or the light switch it self

any idea's

thanks guys

 

The first thing I always do with any unknown electrical problem on a Honda is check the grounds.

Nice car. I have always liked the Legend Coupes.
