No Power to Engine - UPDATE

 
the issue was a faulty isolator and the batteries was not holding a charge, all good now and motor started first kick without the choke and seemed to have more power with new batteries, thanks to everyone especially wifecallsmegrumpy 

Cheers

 

Hi Guys my Johnson 140HP 4 stoke aka Suzuki has lost power to the ignigtion and to the tilt/trim, power to the accesories is OK, I've check every fuse I can find including the one's in pic located in the motor and the someone has suggested the Power Harness Fuse, can some point me in the right direction ( or post a pic ) where this fuse could be located ? 

TIA

Cheers

Where are you located? If your near Southern River I can help.

Do you have 12v at your engine. From the main battery lead?

NOR  and no 12V on the Red & Grey/White cable with battery switch on 1, 2 or both and both batteries 12.26v which thought was a bit weird both batteries having the same voltage ?

Those wires with the white cloth like shielding on them

Seem to get excessively hot on Johnson / Suzuki 140's. In particular I have seen the plastic connectors half melted with heat. Might be worthwhile checking those for good connection. There are 3 wires much the same from memory. Due to the level of heat the wiring sometimes goes a bit black and won't take solder either (if you have to replace the connector) so some of those 240v electricians wire termination plugs work well in place of the factory connector plug
