Question about Pramac Electrical Supplies
Check and replace the spark plug, clean filters and try again. If this doesn't fix it, it is probably the carb. Clean it and try a SMALL squirt of starter fluid

SOURCE: low power
firstly i would do a full service on it , all filter and fluids , oil/coolant water,fuel filter(s) and air filters
pay attention to any water seperators , check all fuel line connectors and unions are tight and in good order ( drawing a small amount of air into the fuel system if often the cause of ''a lack of power '')
check your diesel as it absorbs moisture and can severley effect the running of an engine .
if this has no effect
get a rag /goggles and the right size open ended spanner and slacken each fuel injector nut whilst the engine is running , listen for the engine noise going down , if it dosent this means the injector is deffective ( might need replacing or cleaning ) do this to each injector in turn , be very careful as you do this , the diesel is at 200bar pressure and can injected you ( hence the rag )
a final one is the fuel lift pump may be deffective , they often partially work and starve the engine at maximum revs , depending on your engine this will be an electric one or driven directly from the engine block , just follow the fuel lines from your diesel tank ,.
hope this helps

Start looking at your safety circuits.
1. High water temp
2. Low Oil
3. Low water etc...
From the manual these are the protection circuits.
• Engine protection: low oil pressure, high engine temperature.
• Genset protection: under/over voltage, overload, battery charger failure, battery voltage out of limits,
under/over frequency, start failure.
• Circuit breaker protection: IV poles.
• Differential protection.
Any one of them will trip the fuel relay closed. What you may be able to do is disconnect one at a time each protection circuit and see when the fuel relay opens. (Make sure to reconnect each one if it had no effect on the fuel solenoid)
Once you isolate which circuit it is in then you can chase wires or change the bad switch.
Thanks for choosing FixYa.
