My bow graph is acting goofy, if I run the HDS 8 up front it shows around 10 volts, if I put the hds 10 up front, it shows around 9.4V and blinks on and off. At the same time either graph will show about 12.4V if I plug them in at the console. The bow mount is hooked to the original BCB wiring, the console is wired direct to the battery. Does it sound like a battery issue or front wiring? thanks, Mike
I had a similar problem. It turned out to be in the fuse connector that hooked to the locator. It was the spring type fuse holder. Replaced fuse and holder.
