What the frig........I don't know where?

I've been having some kind of electrical problem. I cleaned the ground wire from the battery to the chassis. I can't find the ground from the firewall to the driver side cylinder head so I can clean it. My car draws power whenever I turn on the heater or the defrost. It also does it wheneve the fan comes on. It drops all the way down to about 100 rpm at idle & almost stalls out. The other day my car died, I turned the key and nothing. I have a new battery, the charging system is fine (12.5 V with engine off & 14.8 with engine on). I had to make a spark on the pos. terminal to start it. Now my wipers won't turn off. I have to pull the fuse. Anyone ever experience this problem. I'm going nuts
