Starting trouble

[chucker]

Have a small yanmar marine Diesel in a Viking 28 kit boat. Was working fine. Then my wife pulled out and cut the wires to the fish finder, GPS, radio, speakers, sniffer and lights. Now the engine won't turnover. We've charged the batteries and the cables seem fine. Has cutting the wires opened a circuit that affects power to the ignition or starter.

Very likely, given what you’ve said. First place I’d look is at the ignition barrel itself, assuming the items that were removed, came from the local of the dash wiring perhaps ? Have you power to other things still ?

Thanks. Nothing, no guages, when key turned on - no turnover with fully charged batteries. The GPS or depth finder went to dash wiring. So we've opened the circuit. Any ideas to start it.

Ask the wife?
Do a check from the batteries, through the isolator switch, any fuses and ignition switch. Could be the negative that is open circuit so check that too. Do you have a multimeter?

A great deal depends on you confidence and ability in being able to fault find electrics.
You'll stand a better chance if you've a wiring schematic, but I do sense that if you'd either of the above, you'd possibly have had a row with your wife, and not have asked the question on here.
Boat electrics are notoriously variable from one to another, and I see that yours is a kit yacht, which unless you built it yourself, or installed the electrics is going to require good basic knowledge to get back together.
It could be that you're lucky in that the wires were cut 1/2 way along, and are all of different colours and simple to rejoin.
Best of luck as they look a very nice boat.
