Any suggestions on what can cause this. This sled was taken in and they said it was a fuse. They replaced the fuse and it only fixed it for a few miles and it blew again. I could not find any recalls. Is there a way to access a wiring diagram for this sled.

Thanks guys...

Change a fuel pump. you have to find out which one is drawing too much though

wow what dealer you use
I want to make sure I never ever go there!
my dealer had the fuel pump in stock
and had it done the next day
there are dealer notices out on the low psi pump
when they go bad they start blowing fuses
then it will quit working
low psi pump thumps when it is working
high psi buzzes when working
you should here both when you energise the sled

The low pressure fuel pump fixed the problem.
I was able to buy the pump from NAPA. I remote mounted the pump using both steel and rubber fuel lines.
It takes a little extra time, but is more than worth it as a possible time saver in the future.
You can hear the pump pulse when the pumps are activated and you pull in the recoil starter.

i installed a new low psi pump from napa and it pulses oppose to thumps as old one did, but psi is excellent 61-62 all day
