hello all,
I'm a bit frustrated, if anyone has had this issue, ,,,, Genny quit while under load; found blown ignition fuse, blew again, so I found shorted out water temp sender,, replaced it, genny ran an hour and started blowing fuse again. But temp switch checks out ok(no Short) any ideas??? hmmm

Check your oil pressure sender.

I had a similar issue. Kept blowing the low .7 amp fuse and found it was the oil pressure sender.
 
hello Pete,
I pulled two oil pressure switches, one is in the open position one is closed, not sure if that is how they work, but they are not shorted to ground like my water tmp sender was.
