I have a 1986 Mercury 150 XR2. A local dealer repaired the engine and removed <br />the voltage regulator from the engine. He told me it was malfunctioning and it was not necessary to replace it. I have been running the motor without it the last two years. My fishfinder has been having high voltage problems and I had small gauge wire under the center console burn-up. I figure before I fry the fishfinder or burn the boat, it might be a good idea to put it back on. <br /><br />I purchased a voltage regulator (Quicksilver 88825a 7 1090 small voltage). Problem is, I can't figure out where to mount it. The old one was removed by the marina mechanic. I've checked a manual I bought for the engine. No <br />mention of the voltage regulator in it. Picked around the engine pulling a few things off looking for likely spots. It mounts with two screws. Two posts on it, one post red, other yellow. I'm a novice on<br />outboards, but, I am hopeful I can install it properly if I can just determine where it goes. It's about a month wait (out of the water) to have it done at the shop right now. <br /><br />I am hoping somebody will be able to help me out with advice about installing it. Any help you could provide would be greatly appreciated. Thanks.
