Title: Fuze blowing
Post by: Detomo on October 12, 2025, 01:04:33 pm

Hi Peeps , :((


Need some advice , trying to set up my electrics in my boat before I install inside the hull.


1. using a p94, connection to a p102 as per diagram for twin motor and bow thruster.
2. also using a p93 for the bow thruster
3. using 3 x 15 amp fuses
4. using 2 x T500 geared motors.
5. using 3 x p95 fuse boards.


I turn on the tran then switch on the p102 the top fuse blows instantly, all the wiring are connected [tight] 
Does anyone know about the fault and how to fix this issue,  >:-o

#1 task is to use a meter on continuity range to look for a short. Pay particular attention to suppression capapacitor wire touching a motor case.
