See full version: 60 amp fuse on suzuki 115hp
Without a multi-meter, I can't diagnose things. I do know that all my pumps and high draw circuits work fine. Bad VM?. Low voltage at my ignition switch? Bad charging circuit? With the day getting late and being drenched in sweat, I decide to move th boat from the launch dock to my assigned slip. I'll continue with trouble shooting in the morning.
First let's look at the trim switch.
You hit the remote trim switch to trim the engine up/down and nothing is working. The wiring to the trim switch relay is independent of the ignition wiring but shares the same WW power feed. This allows you to raise and lower the engine without turning on the ignition. When it doesn't work- the cause will usually be related to a power failure with the WW. It can be the switch, but that seems to be rare. The trim switch on side of the engine operates independently from a different power source.
Next: turn the ignition to start/run - no response.
The ignition switch does several things- in the 'ON' position it is the primary power source to the ECM. At this point, for 4 cycle engines, a relay turns on the high pressure fuel pump. You should hear this pump. Obviously when the key is turned to 'START'- the starter relay engages and through the engines main power source, the starter motor starts the engine. One step before the starter kicks in, the 'neutral' switch must be adjusted correctly, so as to prevent the engine from starting if it is in gear. However, any interruption in power to the WW- none of this happens.
.
So what has gone wrong when these two situations happen? Usually - a lack of continuity of power in the WW or a ground wire failure.

Re: Locating Fuses on a 40 hp outboard help more
Thanks Fin, I'll try that out this weekend.
Thanks for the help, I will look for it. I was also thinking about checking the neutral control and the key switch. What do you guys think? more
I found one small 20 amp fuse on the left side of the motor, which I think is for the tilt. Can someone please tell me if there other fuses and where?
