Electronics cut out

ed_dash · 25 July 2010, 00:29

Apologies for the lack of information but im away with work, and im only going on my missus say so.

She used the boat a few weeks ago and the chartplotter with echosounder occasionally turned itself off. She said it happened when she was transmitting on high power on the VHF. Im thinking that the leads from the battery arent up to carrying the amps needed by both the VHF & Chartplotter / echosounder. I didnt do any of the wiring nor have a i changed any of the electrics on the boat.

Does it sound like a simple rewire job with higher capacity cables?

What diameter cables do other people have for their electronics?

Cheers

Probably a bad earth or corrosion on a connection somewhere - fuseholders can be prone to this.

ah, that would make sense, the inline fuse holder is outside the battery box at the stern. Im guessing that even though it is a rubberised one it isnt water proof. So it could well be that. I will cut it out, and move it to the console end, then test before replacing the actual wires. Pretty sure i already have a spare sitting around.

Thanks

What he said. The VHF will be drawing about 1 amp when transmitting and the sounder is a hungry beast. As your cables were a big enough diameter before - they still should be.

I have a day in the console scheduled for today - similar woes - an 80 mile thrashing yesterday seems to have jumbled the spaghetti a bit more

FWIW, my power dip (TX problems on the VHF) was a very badly corroded earth wire. The dead fluxgate compass had popped the positive wires from a spade connector crimp. A good tidy up was needed throughout

That should read 6 amps

Check condition of battery also, I had my VHF,GPS,sterio go down and then my engine played up, found fault in the battery, switched to second battery and all ok again.

What was the fault in the battery?
