Missing parts
« on: July 08, 2019, 12:21:21 pm »
I need rectifier and regulator to my definitely last CB750A/sidecar project.
Is it possible to use CB750 Dohc or GL1100 combo rectifier/regulator?
Modification to wiring? Connection diagram?

I can only share what I've read - and then remember (which is far more difficult).

Others have had problems with non-CB750A regulators - because the regulators weren't "matched" to the field coil.

It is my understanding that the field coil of other bikes do not require as much current, and some regulators just can't deliver sufficient current.  Low voltage was the result.

I suppose if you do enough "homework", and determine that the field coil demand, for example, on a later bike was comparable, then I see no reason why it would not work.
1978 CB750A (upgrading very, very slowly)

Past bikes - Honda: SL350, CX650C, CB900C, CB1000C, CM450A; Kawasaki: several 1972 750 H2's; Suzuki: TC90J.

Bikes I want: CX650ED, a mid-sized japanese V-twin with ABS.
