battery dead again 5th time this year

Basic electronic troubleshooting skills are to cut the problem in half immediately. Do you have a charging problem, or short???

Measure the battery with the engine off. It should be about 12.5vdc. Then start up the engine. Measuring the battery now with the engine running it should be 14.5vdc, because that means the alternator is charging. If not, then a charging problem.

Pull your neg battery cable. Put an ammeter(multimeter on amps) between the battery post and cable. With the key off and doors closed, there should be NO current draw. If there is, then a short.

I just read about the use of dielectric grease and found that it's not a conductor but an insulator. It said to use WD40 on the actual connection and dielectric grease to help seal from water.

I don't know if its true or not, but if it is then dielectric grease would not be something you'd want to put on the connection points.

I just bought a new set of spark plugs & a new wireset from AutoZone. The sockets of the wireset are pre-treated with dielecric grease. They also sell dielectric grease packets which instruct you to coat the spark plug insulator & tip with the grease. So much for dielectric grease being a insulator!!!
