Hi Everyone, my first post on the forum!!!!
I've had a few issues lately with my Honda90, which has round 1200hrs on it and up until recently has had the usual Honda reliability. A couple of months ago I had a water pipe split, the one that goes from under the vapour sep into the side of the engine block, which resulted in the engine hydraulicing on the bottom 2 cylinders but causing no lasting mechanical damage. However cut to 2 months later and one day while travelling out to sea the engine just cut out from full speed, very slight beep from the buzzer and momentary flicker of all the lights on the remote but no continuous alarm or lights. Turned the ignition off and back on, engine started up no problems and ran the next 4 hours without issue. Next trip out, on initial turning of the ignition key, no lights or double check buzz, gave the remotes a tap and everything came back to life, engine ran all day with no issues (12hrs).
HOWEVER........ next time out, no lights, buzzer or anything on ignition switch on. Eventually traced problem to main 14 pin harness connector under engine cover which had the dreaded green verdigris corrosion resulting in one the pins becoming very thin and breaking off while I was trying to clean it. New harness ordered from main dealer (£160), however when I fitted this I still had same problem, no lights or double check buzz on ignition. Eventually traced it to the same connector but the female side of it on main engine harness side. One of the female connector receptacles has partially corroded away as i cannot see the springy looking part of the female side. It was on the Black/Yellow wire which looks like it takes power from the ignition down to switch the main relay on? I managed to do a bit of a Heath Robinson type repair by dropping some strands of tinned marine wire in the female side and remaking the connector after having given it a good clean with electraclean and applying silicone grease. The engine then ran fine all day (12hrs) with no issues at all. However, it is still on my mind, so what i was wondering is can you replace just one of these female pins in the connector (2.8mm??) or would i be better snipping this wire either side of the connector and either soldering/shrink-wrapping it or crimping/self-amalgamating tape it all up? I didn't really want to go down the road of replacing the main harness on the engine itself. What do you guys think?
On another note, since flooding the engine with water, the trim/tilt gauge is not working, this was the initial problem that alerted me that there was something wrong, as it was giving some funny readings. Checked the sender and this is free, not sure if this is a 14 pin connector issue as well maybe?? The 3 pin connector it goes through looks fine, the only signs of corrosion were on the 14 pin connector.
