However, I've got a bit of a problem. With everything off, there is a draw from the battery of about 8amps. With it running, its about 15 volts at idle and 17-18 revved a bit. When I take the cable off the alternator (engine off) the draw from the battery goes away, regardless of whether the plug in the back is connected or not. Is my alternator/ regulator toast? It was working fine before I did the frame swap/SAS. Any ideas appreciated. 1989 3.0 5 spd extended cab with more rust than should be legally aloud, soon to have a D44 front and D60 rear Re: alternator problem?

Looks like possibly time to rebuild or replace the alt. 1989 Toyota SR5 DLX SB 1995 Toy DX XTRA Cab 4x4 1989 Dodge Raider 3.0 V6, 5 spd, Michelin LTX series, bouncey seat 1988 Dodge Raider A/T w/Offroad Package 1959 Corvette 1977 Z28 1979 Honda CBX 1000 6 cyl Re: alternator problem?

If the regulator is bad it will increase when the engine revs. You should get it fixed very soon or you will toast your battery.
