Thanks to all who made suggestions over the last few days on my '73 with coolant leaking into the combustion chambers, I don't have it fixed yet, but I'm going to tear it down again this weekend and check the head again, then if all's ok I'm going to very carefully put it back together. With my fingers crossed! I now have another problem, and if you Z people don't mind I'd like to ask advice even though it's not a Z. It's my daughter's '86 Suzuki Samurai. It is a VERY simple car, but I'm baffled. A week ago her battery went dead, it would not hold a charge for more than a day, so I put a new one in. After a couple of days the new one was dead. I then to be 100% safe replaced the alternator and battery cables...thats every thing in the charging system. After a day, the car died again. Right now I am at a loss. I suppose that the new (rebuilt) alternator could be bad, but I really don't think so. Any ideas?? The voltage regulator is in the alternator, even the Suzuki Factory repair manual has no other suggestions. Thanks!
