Etec 225 HO mystery

Any one hear back from Bass Buster regarding his engine shutting down when he uses his jack plate. I have the same problem and no one seems to be able to figure it out.

Move the battery leads for the jack plate to one of the trolling motor battery's, that should fix your problem.

Thanks Rusty. I did that, works fine but does not solve the mystery. I'm one of those guy's that has to know exactly what the problem is. Hooking to the troll battery only by-passes the problem, it does not correct it.
Thanks agin! http://www.bassboatcentral.com/smileys/smile.gif

TopPop I just went with Rusty said and moved it to the troling motor he has helped me bunch in the last month. Its not going to draw much off the trolling battery anyway and I recharge everytime. I would like to know the resaon also that is how i am too everything has to be the way it is designed to. but have not gotten any answers from Ranger, BRP or Bob's Machine. Rusty did say the Etec"s are very senitive to voltage so that may be it if you hear something please post it

what are you running the Etec on

Hey Bass Buster, I am running a Z21, 10" jack plate, full fuel, 2 people & tackle 69.9 GPS and loving every second of it.
I have checked the amp draw on the jack plate and its with in the range it should be. There is a little fluctuation in the voltage but very minor. Its seems that when the jack plate exceeds an amp draw of 24-27 amps thats when it affects the engine. (By the way, the amp draw can be as much as 74 and be normal). The only time this occurs is when you first move the jack plate under a load. (Like up when idling, or up or down while on step). Once the jack plate is traveling the amp draw is minor. I am waiting on BRP to send a rep to help solve the mystery. Obviously there is an interferance problem between the engine electronic's and the amp draw on the jack plate. When my problem first surfaced it only did it jacking up or while running on step jacking up or down, now it will kill the engine at any time.
Guess its kinda hard to design for these kinds of unforseen problems.
(But I still love my E-TEC!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! http://www.bassboatcentral.com/boardstuff2/beers.gif
I'll keep ya posted, call if you need to share info 337-256-3890

Mind if I stick my .02 in... I'll presume that the JP is controlled from a switch at the console that operates relays on the JP that feed the motor. It's drawing 24-27 amps with spikes to 74. That's a lot and way more than enough to cause all kinds of voltage 'irregularities'.

This can be minimized by using the heaviest wire that will fit to feed the jackpale motor. I bet that the wire from the motor to the JP is 10 Gauge at best. You can't run that much current thru a puny wire. The wire itself will begin to act like a resistor and drop some of the voltage. As the voltage level drops, more current is drawn by the load (JP motor) resulting in more voltage being dropped across the wire.

Check the JP motor, what is it rated at (volatge and max current draw) If the current you are drawing exceeds the max rating on the motor you may need heavier wiring, or the JP motor is defective, or the JP relays are getting crusty inside. Hook a voltmeter and see what happens when you operate the JP. Move the VM around and check voltages at a variety of locations.

I did this once already but only at the terminal connections. I did not check voltage at diffrent areas. The voltage barely fluctuated. I did not check wire size, but will tonight. Is it posible that at the jack plate motor the voltage could be diffrent than at the terminal connections?
Also when you say "current draw" are you refering to amp's or voltage?

(Thanks for the reply)

Current is AMPS Voltage is a Potential. 5 VDC at 200 amps will kill you. CM

Only takes a milla amp to kill a man but if the amps are low enough a human can withstand many thousands of volts.
