Hi All,
I acquired an LT133 that sat for the last 3 years due to electrical issues. The owner was told it would cost $850 then to fix it so he gave up on it. I'm excited to tackle this electrical fix since the rest of this Mower is in amazing condition and I really need a riding mower.
I pressure washed it and then leaf blowed it to dry it quicker and to not let water sit to long on any metal/electrical parts. Overall this mower looks in amazing condition for a 21 year, or more, old mower.
Before even starting it I bought the following...
The 12V 300CCA battery was dead, even after trickle charging it, so I bought a new 12V 300CCA battery.
I bought a new 3-position JD ignition switch since taking apart the old one revealed it was filthy inside the housing and their cheap enough to replace.
I bought a new RED JD Positive battery cable since the old one had very little of a metal connection due to the metal dissolving away.
I bought a new JD Solenoid. Cheap enough to replace.
I carefully looked the mower over before even attempting to start it.
I found 3 issues....
ISSUE 1 (found before starting it) I found that the VR melted a few wires just below the VR. Photos attached.
After cleaning up those connections, I was able to start the mower and it ran at low and high rpm smoothly BUT when I went into gear or engaged the blades it stalled out.
While it was running it also starting to overheat those melted wires again so I shut it down.
I've read that VR's overheat and many other starting issues are due to a bad ground. I traced all the wires and cleaned up all electrical connections.
ISSUE 2) I discovered a Ground Wire to/from the Seat Safety Switch cut with around 6 inches of the wire missing. I simply spliced that wire back together. 1 Photo attached.
ISSUE 3) I then discovered a Ground Wire to a Relay unplugged, wrapped in electrical tape and tucked under a bundle of wires below the Relay closest to the Solenoid. My LT133 has 2 Relays. This is the inner Relay. The outer Relay seemed to have all its connections properly secured. Photos attached.
Why would someone unplug this ground that is connected at the engine block, then goes to the relay mentioned above and then goes up to the ignition switch? Wouldn't this cause a bad ground?
I'd like to to plug it back into the Relay and start the engine to see if I have any VR overheating issues but want to wait for feedback first from anyone who can shed some light on this. I basically don't want to fry anything else on this mower.
Thoughts and Thanks so much for any feedback you can send my way.
