TR 270 Electrical issues

[HGarcia12]

Purchased the machine a few years at an auction. Using it on the ranch so no hard work. Started having problems with the electrical controls on the joysticks. It wouldn't unlock to release the attachment and some other issues also. Took it in to the shop and they ended up cleaning the valve and replacing the ECM. Also, had to clean up all the wiring harness connections at the fuse panel cause of some corrosion. A year later, having some of the problems again and then some. No lights, A/C compressor or blower, radio, self leveling is always on. Any input would help.

Just wondering if you are having a grounding issue? Do you have a shop manual for this machine? Electrical gremlins on these newer machines are almost impossible to exorcise without a wiring diagram, unless it is something very obvious.
