I'm expecting this is new enough to use the 4 stroke and has similar wiring to the
newer Apex , Lots of suggestions when you google your exact issues . They all lead back
to this site for solutions, but not always your model. Apex etc.
Frozen relay ?? BUT my Apex is full of bridge clips and the ground versions corrode
and lose contact . Some can be cleaned , some are eaten away. My headlight had
the cap melted away and dark inside . Some will clean and others cut , strip and solder them.
There are some good pictures on site. They are usually black , size of a little finger tip
and have a cluster of black and sometimes brown wires leading into them.
Try a heat gun (not melt gun) on relays first.. they seem to hide them in left foot board.

Desperate act would be to carry wire strippers and a mar connector for "field" repair.
Currently my screen shows "similar threads" at bottom. 1st one is "wont start- no power to dash"
good hunting
