Subject: Re: 93 900 turbo battery charge


Hi, Bill, I have a '93 900 Turbo and have had a similar problem. I bought my car used a few years ago and it had previously lived in Florida. No rust but it had dry rot on the tires, and the electrical has been a little wacky. I wonder if the electrical had a little rot as well? Anyway, when I first got it, batteries would last maybe 6 to 8 months, and then be totally dead (I would always have to recharge the battery in winter before use). The dealer said everything was fine in the charging system, but the RS Strauss guys were getting a little tired of swapping batteries for me every few months. I replaced the headlight switch, some of the climate control switches, the radio amp in the console which had all been tempermental. Then I took out the non-functional but still connected Alpine alarm system which I suspected might be a drain. The current battery has lasted through the winter - probably at least a year at this point - and still seems pretty strong so the alarm might have been at least partially to blame for the drain. But there are still a few flaky electrical issues. My interior light sometimes stays on even when it is in the "off-when-door-closed" position. I have taken to leaving that switch in the full off position. And other switches, like the seat heater control are flaky, and crackly. I seems to me like I still have some very slight drains on the battery and since I only drive the car on weekends, this may also contribute to the weak battery. It sounds like you have a good plan - monitoring the drain on the battery while it is not in use. But how you can identify the culprit if you DO have a drain I'm not really sure. If you park your car outside, you might be able to compensate for this with one of those solar battery chargers that keeps your battery "topped off" in charge when it is not in use. They sell them in all those gadget catalogs, like Heartland America. Here's the link to their unit - it sells for $30 - http://www.heartlandamerica.com/Item/default.asp?SKU=9973&Prod=44771+9403+ 94964+94971+9973 I haven't tried it, but this might be an option if your battery drain is low enough for this to compensate and if you park outside. Of course, you could always just keep a fresh battery in the hatch or the trunk - or one of those DC power boosters for instant power. At least this way your wife could feel a little more confident driving it around. Anyway... hope that helps a little. Misery always loves company. (-: -Chris
