OMC shift assist module problem

[subcrx]

shift assist module not operating, The previous owner installed electronic ignition . is there a way to make it compatible with it?

Re: OMC shift assist module problem

the new ones work with it however i disconnected mine 4 years ago never had a problem i keep my idle at 500 rpms makes it easier to shift

Re: OMC shift assist module problem

im not telling you to disconnect yours some people will tell you that your shift dog can go i believe them all im saying is i disconnected mine it is my choice my boat and i do what i want with mine its up to you if you want the esa if you do get a new one that works with electronic egnition.im still running points.

Re: OMC shift assist module problem

I have set idle to 500 before, thats too low and charging is bad. I found this, I know I dont have the full distributor but im sure this is similar, scroll down to the second page. and tell me what you think. will only cost 5 dollars at radio shack to make.. http://www.mr-gasket.com/pdf/Mal_ESA.pdf

Re: OMC shift assist module problem

book says 600 rpm my boat is good in water at 500 charging good.cant give advice on esa.better minds here hope they chip in good luck

Re: OMC shift assist module problem

That's the same as the Pertronix diode resistor fix, some guys say it works and some ???? There is a company CDI/Rapair that builds a compatible ESA module for these, I'm pretty sure iboats doesn't carry the parts but you can see them here

Re: OMC shift assist module problem

Boatfix carries them too...at least they used to.

There is really no good reason to not have the ESA on there. Your shift cable will last longer if you have it. An ESA is way cheaper than a shift cable and you are definitely safer if you can get your boat out of gear easier.

Re: OMC shift assist module problem

I put together the diode setup, im gunna install it tomorrow, Ill see if it works. Right now I know I have twelve volts going into the esa, but no power at all going into the switches. Would you say my esa is shot or is it possible when I install this circuit it will magically come to life.

Re: OMC shift assist module problem

The diode fix does work. I put it on mine when I installed the Pertronix. I have since installed the newer ESA and removed the fix. I later had an intermitent problem with my ESA. Finally found a bad wire (connector) between the ESA and the coil. Ran a bypass wire around the connector. Now all is good. Something to check for if it still doesn't work. I would hate to know I had to do without my ESA. Tough times at the dock for sure.

DO NOT expect to find voltage on those switches, they are wired into the negative/ground/return part of the ESA circuit. The only place to check for voltage is the purple wire on the 2 wire conenctor which should have 12v. If you suspect a switch you need to unplug them at the 4 wire connector and use an ohmeter, the interupt switch goes through the normally open points and the overstroke switch goes through the normally closed points.

Re: OMC shift assist module problem

i honestly have no problem around the dock or driving it on the trailer.22 year old boat.i had problems with the wiring harness when i first got the boat.i ran a wire from the battery straight to the coil with a switch on the dash that i turn on just before i turn the ignition key.i was going to install a push momentary switch in place on the keyed switch but this worked for 4 years now.esa wouldn't let me get past 2500 rpm on the water but in the driveway i got full power thats y i disconnected it.drove me crazy.6 times driving to the dock.than the tilt power ran another wire to the tilt.left both wires now i know i have good power.

Re: OMC shift assist module problem

diode fix is wonderful, amazing. Just ran it earlier, it works well. now I need to fine tune my cable adjustments. it kicks on but wont kick off, wont reach to the second switch

its funny you say that, I had a continuity problem at that same exact spot, I bypassed it as well

What model OMC are you working on?

Re: OMC shift assist module problem

87 cobra with a 5.7 engine. Had to straighten the arm on the first switch, Im guessing the second switch is the relief

Re: OMC shift assist module problem

The second switch is the overstroke switch. It kills the ESA only if needed. The cam that operates the shift inteupt switch should return to it's "home" position as soon as the bind is off the cable-in other words once the drive has shifted to nuetral. You do need to adjust (maybe replace) your cables but not to make that second (overstroke) switch.

Re: OMC shift assist module problem

good to know, ive been toying with these cables since day one

 

[chiefalen]

Re: OMC shift assist module problem

the new esa don't use the overstroke.doen't even have the plug for it if u go with a cdi or rapiar.it has a timer my friend had one and it a byatch around the dock cause it stays on for 3 to 5 seconds.thats y i never put one on.like i posted im not telling anyone not to put one on.

Re: OMC shift assist module problem

Twin 89 5.8L. I installed two of the CDI Electronics ESA's early last year and don't have the 3-5 second issue you talk about. Also have Pertronix without diode fix and everything works great. One problem I did have was I upgraded the coil to a .6 ohm Flamethrower and burnt out the ESA's. Found out from them (CDI) that this will burn out the ESA. Today they come with a warning and tell what's needed to fix it. In my case it was a 2.5 ohm ballast resister that they sell for $25 each. Coundn't find them anywhere else. Oh, they did replace my ESA's for free as when I bought them they didn't have the instruction warnings.
