Hiya Guys,
Well after a day and a half of fault finding why my 15 kva gas driven genset wouldn't start I found the start/stop relay to have a blown coil. This is after changing the motor coil and condensor and touching up the points dizzy cap and rotor button with a bit of emery thinking one of those parts had expired
Looking at the coil I'm assuming it's a single pole double throw relay which is rated at 6 volt with a resistance of 15 ohms. As I'm not real fluent with relays I'll describe it the best I can to see if I'm correct in my assumption. When I say the relay is old I mean old, now the relay has a power and a negative wire one one level then on the upper level on each side is two wires on each side. Now one side engages the starter motor where the other side cuts the engine. But with only 2 wires to control the relay I reckon when starting the motor the polarity is positive engaging the first throw and when switching the motor off the polarity reversed engaging the second throw.
As the input is straight off a 12 volt truck battery I can't see any reason for not using a modern 12 volt relay to replace it.
If anyone would like to help me out on this I'll appreciate it as trying to find a qualified person to come and fix proved fruitless.
Cheers Bryan
