    Not sure what happened. I bought a used implement hitch, hooked it up according to the directions. Red wire hooked to load terminal of the 40 amp circuit breaker, green wire to ground. When I pushed the switch to raise the hitch something was damaged. The hitch did not move and the mower continued to run normally. Turned engine off and now electrical system is showing about 8 volts on the meter, starter will not engage. Seems to drain what little power is in the system with the key on start.
    I've checked the motor on the hitch, it does work normally with 6 amps supplied by a battery charger.
    With the key out or in the off position I have 12.6 volts at the battery, circuit breakers behind the battery and at the alternator. Same voltage with key in "on" position. The instrument panel is showing 8 volts, horn is weak and oil light is dim. The relay under the time delay module has 8 volts coming to it.
    Any ideas what might have happened?
    Was planning on playing with a new toy today, not killing the mower.

    After 3 hours I gave up and took it to the dealer today.

    Hey, just saw this thread....

    What's the verdict?

    Won't know until next week. They suspect I fried a relay. I could restore 12 volts throughout by unplugging relay "a" but it feeds several things including relay "e" which feeds even more stuff. Felt my time was better spent working rather than trying to figure this out.

    Gotcha.... I have unplugged relays. In fact, I have one unplugged right now.....

    It got me through the end of the season but luckily there is a foot of snow on the ground currently...

    I will have to get it taken care of by the spring!

    Shop is replacing the wiring harness. Don't see how that got damaged, but if it fixes it I'm happy.... until I get a bill for the repair.

    Got it back. Repaired wiring harness, new battery, cleaned some contacts. Interesting thing is I did have the electrical connections right. $129
