Electrical Problem

[SlowWhite]

a few weeks ago I was talking off my exhaust manifold and turbo and touched my socket wrench against the alternator, the car still had power, and it caused a spark.

I had the battery charger attached to the battery for probably 4hrs so that I could keep my fans running to cool down the exhaust manifold faster.

Anyrate ever since My battery isn't holding a charge anymore (was bad to begin with, had to charge it if I hadn't driven my car in 3 days or more)

Anyrate now when ever I hook up the charger and it's on "Boost" my lights click on weather or not the knob is turned or not and don't turn off unless I lower the voltage, If it's on normal Charging cycle the lights work perfectly.

I've checked all fuse's all of them were fine, I've switched out all the relays pertaining to lighting what so ever, as I can hear the head light relay click when I up the charging to boost. As well as feel it click when I flick the power on and off the charger.

I'm going to be buying a new battery this week (30 minute drive to the only place in the area that carries the Type 51 yellow top) But not sure if that's going to fix the problem. I know it's something I need anyways as it wasn't holding a charge anyhow.
