I'm new to this site so any help would be appreciated. I'll give you a rundown of what has been going on.
This all started with my ignition switch going bad. I have replaced it with the correct model thru Ford/New Holland and currently have it wired correctly. I say that because the first time wiring it, I had wires mixed up on the switch. Now that I have corrected that issue the mower starts every time. However the mower will run at full throttle with blade running (or not) for a short period of time, then it will die/blowing the 25A fuse. The mower will idle for over 30 minutes without blowing the fuse. The 25A fuse is not the main fuse to the system. That fuse is a 30A. Could this issue be the voltage regulator? Or something else?
Are you saying engine runs at full throttle just fine but when you engage mower blades it runs for a short period of time & blows fuse? If this is the case try adjusting air gap at PTO clutch. Also check all wiring by hand making sure all connections are tight & secure including ground straps & cables, inspect all connections at backside of dash & look for bare wires, wires chafing to frame, etc. http://www.ebay.com/sch/items/?_nkw...12&_fpos=&_fspt=1&_sadis=&LH_CAds=&rmvSB=true
Engine will idle without issue. Its when I run at full throttle for a period of time that it blows the fuse. It does this with and without blades being engaged. Therefore, I didn't feel like it had anything to do with the PTO, but I could be wrong.
