I have a Titan 875 and sadly the wiring on both 575 & 875 is cheaper than hydramaster should have used. I’ve had wires melt and have been told my multiple mechanics that this is a common issues with this line on hydramasters sadly. I upgraded it myself to larger Guage wire where there had been a problem. Main harness of wires is poorly made as well. Shoot me a message if you want. I’m not far from Sacramento. Be happy to give any advice I can. I have another friend with a 575. Good machine just has some lacking areas in the design as all machines seem to have in one way or another.
