ALTERNATOR

1985 BMW 318

Engine Mechanical problem
1985 BMW 318 6 cyl Manual 160000 miles

Car is a 1985 BMW 318i having problem with the alternator. The alternator would kick in and charge the battery but not all the time.I replaced it and the new one keeps doing the same. I had the new one tested and the guys said that it was good. I think there is a short somewhere but I don't know where.I traced the wired from the alternator to the battery and from the relay box. Dose the alternator have a relay?Or would you know where the problem is?What should I do next.

Be sure the alternator is grounded to the block and check the battery ground too. If not properly grounded, it will not work.
