wellcraft/volvo trim-tilt wont work

[bralos]

New to boats and just bought a 1997 Wellcraft with Volvo inboard outboard. Analog trim gaugle on the dash. The trim is all the way up. When I push the trim button on the throttle it does not go down nor does it make any noise. I followed the wireing harness and where it splits to a larger red and black plug I have power. I also found were the rest of the harness goes to a plug with the rest of the 3 wires. One is hot and I assume the other 2 are the down and up. (Both plugs to side and rear of engine) It got dark before I could test ohmes between the other 2 wires.

I checked the reset on the pump and it is not triped. Also the red on the pump is hot. so I am guessing the switch is bad. Do the switchs go bad where both up and down go at once? I would think one or the other would go and odds are both wont.

I have read another forum where they were having issue with going down but up works. They were talking about relays. I cant seem to see any on the pump or under the dash. Any insight on this?

There is also a toggle switch on the dash. Is this the override to allow it to come all the way up for beach?

If I need to replace the switch is this a standard part or OEM specific? Also how do I remove the throttle (think that is what its called) handle to get to the swtich?


Thanks for any and all help.

OK I dont have relays. I have a relay control box on my unit. I hope that is not my issue at 250.00. The unit I have is the DP-S 1.78. Here is the digram of of the unit.

OK pulled the 3 prong plug and jumped the red to green and to blue. Trim raised and lowered fine. So looks like the pump and motor is fine. Checked the ohmes from red to green and red to blue going to switch while pushing trim switch. Neither one showed any ohme. Pulled the plug thinking the switch was bad. I cut the the wires and no voltage to red. So issue in line from back of boat to switch. The wiring digram shows a fuse and relays. I cant seem to find them ANYWHERE. Anyone have any ideas?

Anyone out there? Hello?
