someone who knows WTF they're talking about will be along shortly, but I presume it's because the ignition is merely activating the solenoid, hence not big current/amps?

Because a high current can't flow through the lead as the solenoid itself should have a big resistance. So I guess that's the first step in investigation - put a multimeter on that circuit to see if it is shorted somewhere.

Thanks lads, but the ignition wire is just connected to the battery lead before the lead gets to the solenoid. WTF ???

Any one got any class A drugs?

John, I would disconnect the battery then measure the resistance between the two points I marked in green on your diag. I don't know what it should be - but if you know the spec of the fuse we can tell you what it shouldn't be! One thing though - do you not have "start in gear" protection on your engine? as that would add some extra wiring (and potential for faults).

Going to have to go buy a multimeter, always avoided electrics up until now. Bloody boats!
When I get one I'll give it ago (thanks again for all your time )
The fuse on the ignition is 20amp
I'm not 100% sure but I think my OB doesn't have a start in gear protection under the hood. It's in the 703 control.

On the top of the engine it says 70AH battery or 100AH battery for cold conditions. I'm using a 110AH battery. Could that be too much?

No, these are minimum requirements. It's still giving you 12v. Just for longer. My 90s have one each .

A layman's tip for lekkie, sometimes it's more important where it's going to, than coming from....

Upon further reflection, I was just thinking that it was a while since we got flung in the bilges - should we "start" something? I don't think I could manage any personal abuse, but I'm sure I could rise to some innuendo, it being Saturday night and all .

Cheers Willk. I'll keep that in mind.
This is starting to consume my life! I know (hope) it's something so simple and it's keeping me from using the RIB.

Try another battery, I had a new one that had been charged reverse polarity and thats exactly what happens when your battery leads are on the wrong way!
