Help wiring 15A sprayer

[optimist]

Tired of dragging my sprayer behind my mower, I'm moving it to my 2516HST, but the electrical connection (15Amp battery clip type) is too short and that's inconvenient anyway so I'd like to try to wire it more permanently. Anyone have recommendations? The owner's manual mentions Fuse E "is for the optional electrical equipments" but that's it...don't know if it's on with ignition or always on or where the heck the "other end" of that circuit goes. Are any other of unused fuse ports actually live?

Thanks

A DMM will tell the tale shortly. If you don't have a DMM get one before attempting any sort of electrical work. You wouldn't attempt mechanical work without wrenches would you? The same applies to electrical work. This one is just great for aumotive work because it measures DC current with a clamp on meaning you don't have to open the circuit to measure current flow.

I have a lot of meters but this one lives in my tool bag.

With a tester like mentioned above you can “tap” about any fuse.
