This message was originally posted on the 444-544 forum. But since it pertains to a system sourced from a 240, it is applicable here too - thanks!
I'm back to working on my '65 PV after a couple year pause, now working on the wiring. Since I'm adding a bunch of new electrical items (A/C, OD, radiator fan, cruise) I've decided to modify the system with a new "street rod" fuse block and associated wiring. The fuse block has 8 circuits; 4 switched & 4 unswitched. I was planning on powering the wipers, radio, fuel gauge, and engine warning lights on one of the switched circuits. I'm wondering if this may not be such a good idea, and I would appreciate your input.
The car's original B-18 was replaced with a B-20 sourced from a '75 240, which came with the period-correct Bosch alternator that uses an external voltage regulator. From what I've read about this alternator I believe that the charge warning light circuit may be essential for providing an initial excitation current to get the alternator on-line (I'm really not sure about that). If this is the case, then it may not be such a good idea to have it supplied by a circuit that is shared with other accessories.
Please help me understand the design of this charging system, specifically the function & requirements of the charge indicator light.
Thanks,
