Electrical issue

Submitted by Bones 79 on Wed, 2017-03-01 20:01

 Hi guys 

Is it possible for the battery 1,2 on off isolator switch in the boat to fail. I noticed on the weekend that the boat electrics can work when the switch is in the off position  this has only just happened as it used to work fine 

 

thanks adam

 all electrial switching mechisams will eventualy fail   so yes its possible  just put a new isolator switch in  and all will be good but sounds like it   has just carcked its switcing mechinasim , sorry but one other thing , never never switch your battery isolator switch with the outboard / inboard  while its  running ,it will draw a large arc  because it is under load 

A it stuffs your isolator switch

B if you have some fuel fumes floating around  your likely to get blowen up
