R26 Replacement Voltage Regulator Wiring
Posted: Fri May 20, 2022 12:55 pm
I have a new electronic VR I'm installing in an R26 and I need some help with the connections.
I have two sets of directions and they don't seem to align:
This one shows D+ as "Free": This one shows 61 as not connected: This is a photo of the board and wires: Assumptions and questions:
The connectors on the board from Left to right - 61, 51, 30, 15.
B+ should be connected to 51 or 30 as they are tied together on the back side of the board.
DF should connect to the melted yellow from the generator.
That leaves D+ and 61 in question. Also, there's a mention of "removing the field resistor from earth"? Does that apply it the R26 and where is it if it needs to be removed.
There is another yellow wire coming from the top that was attached to the top RH screw holding the old VR (see red arrow). I'm assuming it will go in the same place on the new install.
Thanks for the help,
Scott.
