Hello, I have a 1982 Mercury BM 150hp sn# 6101202
Please move to a ranger forum if necessary, not sure if the trim motor is a mercury or ranger part.
I am looking for a wiring schematic of the trim motor used on a 1982 ranger 350v w/Merc 150hp black max.
So my trim switch works going down, but not up. I need to use a dmm on the switch, but want to see if the signal is ok going to the device. the connections look corroded, so hopefully i can clean up a connection on the pump side to get it to function.
However, the "trailer" trim button works.
Not sure if that button uses different wiring / solenoid / relay.
Also, any advice on where to drain/fill this unit without getting air into the system would be greatly appreciated.
My guess is the oil in the unit, is from the factory fill back in 1982!
Pics posted below. The shifter pic; from somewhere online, is similar to the unit currently installed on my boat.
The pic of the ram & pump / solenoid assembly is on my boat.
I know the boat is old, but looking to work through this, as I cant afford a new vexus/ranger/phoenix/skeeter/basscat, etc.
