Hey all. For the 4 months I've owned my 300D I've been fighting an intermittent charging issue. Battery is new, alternator is a reman Saab AL129X with a good regulator, all charging and battery cables are new 4 and 2AWG respectively.
I've traced it to a current draw on fuse #14. Aux water pump is deleted, no monovalve, kickdown switch is unplugged since it doesn't work, tried unplugging the glow timer with no change. With fuse 14 out, it works great and charges at a solid 14.6v at idle. With the fuse in and the glow timer unplugged, it drops below 12v quickly at idle and will not go above 13.2v.
The past few days have been warm enough that it starts fine with the fuse out, other than a smoke show out the exhaust. But I'd like at least my glow plugs to work.
My FSM schematic doesn't list anything else on fuse 14 that I haven't tried disconnecting so I'm a bit lost.
