55.2-59 Battery draining

[mr48chev]

I really don't want to get too distracted or off base in this thread.

Testing the battery you really do have to have it fully charged and then use test equipment that Dsracven mentioned in post 24 that actually puts the proper load on the battery for the correct amount of time and shows the results.

I don't know brand or model but the local Les Schwab tire store (big chain in the Pacific Northwest ) has but it is one of the best and most complete testers I have seen. You need equipment like that to test it right and it will test the charging system along with the battery.

Back to Phungki's truck, from reading what it has and doesn't have there isn't much there to cause a parasitic drain. None of the usual stuff that drains a battery after a period of time if you don't have a battery tender on it. The anti theft system in my BMW draws a tiny bit of power all the time even if you don't have the alarm turned on. It's not a bother if you drive it on a regular basis but drains the battery if it sits for a month.
Things like an alarm system, clock in the radio, an amp that isn't shut off by the ignition switch. light in the glove box that doesn't go off when you close the door, trunk light that doesn't go off when you close the trunk.

I had a student who owned a nice 64 Chevy lowrider that he had a lot of work and money in and left at home when he went to work beause the parking lot where he worked was famous for door dings by careless people. Every morning the battery was dead and he would have to jump it to start it to get to school. we tested battery, alternator and everything else and no issues. We even had the sun scope hooked to it to check the alternator on the scope. After a couple of weeks of battling it he was fussing about it to his mom and she goes "oh, your brother and his friends have been listiening to your car sterio while you are at work at nights." Little bro found out real quick that that was not to happen again and no problem from then on out. Billy's dirty battery in his mid 60's Chevy truck was the other one. That was the first time I had seen that and I have seen it several times since.
