"Well here it goes, Installed
"Well here it goes, Installed control for 1988 Alpha One Sterndrive that I just bought on ebay. Every thing works on the mechanical end but I need to figure out how to wire the system. I will give you as much info. on the control and the respective wire groups and colors. The control has two toggle switches. (one is on the T-handle of shifter and one clips through gunwhale and is at the bottom of mouning bracket and plastic cover. Top switch reads only "Up and Down". Bottom switch reads: Tilt(Up and Down). Also, the beauty cover that hides the shifter handle mounting screw and wiring to top control reads: Pull Neutral and on bottom HI-Flex. There are three small wire harness's and they are as follows:
1) Top toggle switch has three wires (red,blue,green)
2)Bottom toggle on base or cover has three wires (red,yellow,gray)
3)Inside gunwhale at the rear end of actual mechanical control has two blue wires.
Like I said, I bought it on ebay and it said it was a Mercruiser control. I was hoping you guys could identify it for me. It has a red trigger on t-handle and both toggle switches are red. That is all I know.
The power trim pump has two solenoids and is a ARCO replacement,with plastic reservoir,it has a black rubber three prong plug. I cleaned pump really thouroughly last year and tested motor with 12 volts and it seemed to be working.
It looked to be in pretty good shape. I also noticed that the two solenoids were joined by a brass plate. I am guessing that this is where the unit gets power direct from the battery? There is a 3/8 or 7/16 nut that a heavier wire would attach to. The housing also has a red rubbler coating on it. I am going to start here at this point and will take one step at a time as I find out how it is wired. I have a Seloc Manual but would be as well to try and decypher King Tuts Tomb!lol I also downloaded the merc. manual on iboats but for some reason the drive download will not function anymore. The engine manual works just fine but the other won't work for me. It worked about a year ago. That is probably the last time that I attempted to open it. Bondo and Guy were the ones that helped me download and I thank you. I am thinking that the two blue wires have something to do with the shift interrupt switch.(but just guessing) Also, figure that the red wires on both switches are both hots from a fused source. And I guess the other colors on each switch are either up or down. But the problem is where do they go in relation to the two solenoids. I am sure they must go to the solenoids because that is the only logical place (but where?) thanks, Tom"
