Hi my name is Robert...
IF it is blowing all the fuses inside the HWH box then you have an issue with the control box or wiring harness for the jacks.. Might need a shop to troubleshoot this, if you know the series HWH system you have I should be able to send you a service manual, from my experience working on these it sounds like the control box has a dead short if it is blowing more then one fuse. HWH does a pretty good job on there manuals for troubleshooting and you would need a volt meter, if you can tell me the series system I can see what info is available.... Robert
Let me see what I can find... Robert
Click HERE and have a look go through the manual and read all the info and then you can see where to check your voltages, my gut says the control box is bad but you want and try and narrow it down if possible.... Hope this helps some.... Robert
