I'd be behold'n to any of your expert advice on the basic first steps to isolate a very slow battery drain problem. ('87 325)

Right now there are no obvious things like lights left on.

Thanks for the help in advance.

No alarms other than the ABS light coming on after starting. What I'm looking for is whether I need to do step by step pulling of fuses, using a voltmeter, etc.

Disconnect the negative battery lead from the battery. Take a ammeter (I use a multi meter) and hook it up between the negative battery cable clamp and the negative battery post. If you see mre than about 200ma, start removing and replacing fuses (one at a time) until the current draw drops and you now have located the offending system. I would continue the drill using all fuses to be sure there is not more than one system over drawing current.

Fantastic Bear! I'm sure this type of info will help others besides me. Once I identify the offending fuse/systems what are the next logical steps?

Yes, the fuses themselves are fine. It's the systems the fuse serves is the problem.

I'm really looking for the next steps to isolate the exact device causing the drain (fan, light, tach,...)
