 Posted: Thu Sep 29, 2011 10:02 am Post subject: Short in E-Bus Feed Circuit? |
 |
|
Situation - I am using Z-12. I have a diode, which tests ok, between the main buss and the e-buss. I have the e-bus wired to a switch and then to the battery bus per the diagram. For the wire from the e-bus to the switch, with the switch in the off position, I detect no short to ground. Same for the wire from the switch to the e-bus. With the switch on I blow the fuse (10amps fuse with no load on the e-bus). If I detach the wire from the e-bus to the diode between the e-buss and the main bus, the fuse remains intact. It appears that the problem is with this circuit, yet the diode tests ok. What am I missing? (All wiring has been triple checked to conforms with z-12.

It sounds to me that the polarity of the diode is reversed. Have you double checked that?

It turns out that the rectifier diode was defective. I probable shorted it out or something as I was installing and testing wiring over the past several months. At one point it worked and I thought that I checked it yesterday. I ran down to my local electronics parts store and pick up a replacement and everything checks out now.
