Cannon Mag 10 HS issues

[Gill-T]

I have been having reoccurring problems with my Cannons. Blown fuses and motherboards. I run a Big Jon on deep center rigger. It goes up and down. Never a problem. My two corner riggers are cannons. They last a year before boards need replacing. Big Jon and Cannons are wired exactly the same with an inline fuse to POS + post direct to a dedicated battery that only the riggers are hooked up to. Connections to primary battery and perko battery switch. Rigger wires are sized up two sizes so it should not be a resistance problem. See picture of the melted fuse below. It has been suggested I have a bad ground. Connections look perfect with sealed terminations. Getting ready to junk them. Any suggestions?

Check the rubber boot on the up/down switch.  I had one that would eat boards.  I replaced the board and found the boot was cracked and water was getting into the switch.  I replaced the boot, switch and board and the problems went away.

Keep your battery fully charged and this will help with the problem you have with blowing motherboards,it worked for me.

Battery always charged up. I don’t leave out riggers in rain but keep the ideas coming

what size fuse are on the CANNONS ?

What size wire are you using and how long is your run? That includes wire to your fuse holder.  I rewired my HS Cannons using 6 AWG cable with hydraulic crimped ends and circuit breaker for same this season and that has cured my issues with slow speed/voltage drop. You shouldn’t be melting fuse or holder.  Suspicious that is at least part of your problem and needs to be heavier.  Check your Perko switch for corrosion too- those switches due fail.

Same issue last week with my Cannon Mags. Went thru 10 fuses on both riggers on Friday. Next day after leaving riggers uncovered for 1 night no problem with fuses! Definite head scratcher????

My riggers were always covered too Chad but moisture was still getting in the rubber boot.
