Does anyone have any access to original wiring diagrams for a Mac V-25? Had to repair the mast step and the wiring on the boat is shot.
Rewiring an 76 MacGregor 25

Under Sailboatowners forums, it includes a separate MacGregorowners.com as well. Although the manual is under boat info downloads, there is one easier to read in owner modifications with a small diagram but does not show the path of travel for the wires in the boat under MacGregor 25. There is some discussion but where to search, put in MacGregor 25 wiring and it will display some discussion. May I suggest that you go to that forum to post any question on the macgregor 25. It has 24 years since being a dealer for them and simply cannot remember.
These old Ventures were pretty plain jane I believe. At least mine was.
Some came with no electrical at all and I doubt there is a factory diagram.
There shouldn't be very many wires or fixtures to deal with if its a stocky boat.
What you might possibly have:
Switch Panel - wired directly to the battery for power supply
Switch Panel - wire pair to Bow Navigation Light
- wire pair to Stern Navigation Light
Switch Panel - wire pair to Mast Head Light
Switch panel - wire pair to any other devices.
Your switch panel may or may not have fuses (I hope it does).
Not very difficult. If your boat has a liner inside it might be
a bit more of a pain but nothing a little cussing and swearing can't fix.
I'm not saying that your boat should be wired just like this, because over current safety
was rarely addressed in these really old Ventures among other "lets cheap out" issues.
I have since graduated to multiple batteries, local and remote switch panels and terminal blocks,
many many added circuits and devices and am preparing to add 200 watts solar and 110V shore power.
