Thread: Electrical GURU's I need your help

I'll try to check mine tomorrow, time and weather permitting. Does this make any sense? You could use a DPST relay also.

Where/how did you run wire cane pole when you wired to TM housing?

Right on.

I looked at a tabletop type power supply. They have a cord for power and a cord for output. 500 ma would be just fine. I will mount the power module on top of my on board charger prob with Velcro. I will cut the power plugs off both and splice the power cords or join the wires in a new ac plug. This way I ain't gotta fool with but 1 cord. I don't worry about a warranty. Ain't got one anyway.

My electronics were on their own battery up front. This was on my War Eagle Predator. I removed the front minner bucket and made a battery compartment. I ran a wire from the skag up thru the slot on the terrova shaft to the ground side of the up front battery. The ground side of this battery was also tied to the TM battery negative at the TM control board. This worked for me. None of the ferrite beads I tried stopped the noise completely.

EMI/RF noise is inherent. You can't really stop the noise, you can only mask it.

I have no cue what I will have to do with the Ulterra. It ain't got a groove in the shaft so I am told.. My pondtoon has no wiring channels front to aft. I will probably have to add one. PIA though.

My noise is coming through the US2. I was sure hoping the link was the charger. I haven't finished testing yet. I tore down my setup before I thought things completely through. My first thinking was that it was coming from the US2 which is connected to the 998 and then across the ethernet and jacking up the SI on the 798. I gotta go lick my calf over on this one. It may be coming across the power of the 998 to the 798 which are bridged. Gotta hook everything back up except the ethernet cable and see what happens. I sure hope it's coming across the power. I think that would be some easier to deal with.

Ain't it purty?

The bad news is that once the interference gets to the 998, it appears to travel back to the 798 both on the power wires and the ethernet cable. The only way I can be sure of this is to put the 998 or 798 on a separate power source and see if the interference is the same across the ethernet cable as it was with a common power source. I do have a non-hd side imaging transducer laying around somewhere. I guess I could hang it on the TM and see what happens. I would really prefer to put a hdsi transducer on the motor. I think I'll tell my wife that a pair of ONIX units would fix this.

Here is the interference from the US2 with the charger and ethernet disconnected. It is traveling from the us2, to a 998 across the power wires to a 798. The 998 running 2d is OK.

Canepole, when you ran wire from skeg, up shaft and to battery you had that connected to TM control board as well....is that the ground connextion at top of TM or in the footpedal housing?

I hooked on the power board. I tried several places, but this point gave best results. That US2 is a booger. This connect point is the same place near where the US2 fuse wire hooks. US2 wire is internal vs wire I ran external. Same point electrically. Figure it??
