Ha, John has refused to install my kits long before the Epic was even on the market so nothing new there. Now he just has an official sounding reason other than his pride.
I'll exchange that tidy bilge harness for a clean and clear direct to battery harness if you want. Just send me a pm with your address or I can hand you one at Daytona if you are going.
Now, If installed as instructed, the power for the tidy bilge kit is connected directly to the same terminal as the battery cable. If the current from one or even two bilge pumps is enough to cause a significant voltage drop on a #6 battery lead, there is an issue with the battery lead. Plain and simple.
Next, the ground wire of the tidy bilge kit is supplied with a ring terminal and is intended to be fastened directly to the ebox backing plate with all the other grounds. If there is a weak link here, it's the ground. The only path back to the battery from the ebox is through the single ground wire in the stator harness. This wire connects directly to the stator backing plate which grounds to the motor via the two mounting screws. The ground path then continues through the engine cases to whichever point you attached the battery ground wire to and eventually gets back to the battery. If there is an issue with the continuity of any one or more of these many connections then yes, it could cause an issue and adding a bilge kit would only exaggerate the issue. Also pretty plain and simple.
Besides getting the wires cut or mechanically damaged, the two places I see fail the most on the stators are a loose or corroded ground screw connection to the backing plate and a worn or corroded contact surface where the stator bolts to the cases. It is for this reason that Surf Armor stators will all have two ground wires as standard. Not only will this increase circuit capacity for extra items such as bilges, but it will also add a level of redundancy that should keep you on the water longer.
Now, having said all that. I run dual pumps in my ski, thru the ebox, with an Epic and have been for over 3 years now. I have had zero issues with mine while others have had nothing but issues with theirs. (Including many people that do not run a tidy bilge I might add). I have had pumps fail and short out, I have had a battery cable wear through and cause a parasitic drain on my battery and then eventually corrode up so bad from salt intrusion that it wouldn't crank my ski with a full charge even. And my Epic performed flawlessly through all of this. In fact, we even swapped in a buddies Epic on a day it was causing backfiring, kicking back on cranking and had even kicked the engine into running backwards after landing a jump and It ran perfect in my ski. If voltage drop is the culprit, I should have seen at least some sign of issue should I not?
The next time one of you guys talks to John, ask him about the custom wound coils he offers. I can't remember if it's the charge coil or the lighting coil that he does but one of them supposedly has 100 or more extra wraps on it? Pretty sure it's the lighting coil. Both my current JSS stators have this custom coil installed and I have always maintained that this is why my skis are so reliable and why I suffer so few epic issues. Increased output from the lighting coil would help keep overall system voltage higher and above the threshold of interference.?.?.? Just a theory I wanted to run by him sometime.
