I have an fh451v. Recently the clutch started working intermittently so I replaced the on off switch for the clutch and got the same problem. Then I replace the clutch and I still have the same intermittent problem. when I turn the blades on there is a hissing noise coming from the clutch not sure what that is but it happend on both clutches. I've gone over all the wiring and its fine. what could be the problem for the intermittent clutch nor working?

Thanks

Since you've already replaced the switch and clutch, I'd take a look at the voltage available to the clutch--unhook the wiring harness at the clutch and with a VOM, check the voltage with the engine at WOT and clutch switch on. You ought to have 13+ volts at the harness.

Checked the voltage with a multimeter and the dial setting on 9V. I was getting 17 volts at the harness.

9 volt setting ?

All my meters have 20 volt DC setting, You shouldn't have over 14.8 DC volts. More like 13 low 14's......

What is the Spec. Number of your engine... FH451V-????

Electric start or manual start?

Good questions Jeff, I just assumed electric start......

With a manual start and electric PTO, you should just have 2 wires coming off the engine. One for the ignition kill lead and one from the stator to power the PTO... See Wire Diagram below.

With that type of setup you have an unregulated stator which is a single wire that should have an output of 28 Volts AC @ 3000 RPM... See Electrical Specs. below.

Also included is how to test the stator if low output is found... See Testing Stator below.
