E200TXEO tach not working, no charge

[Bruce San]

200 Ocean Pro: tach has been intermittent lately. Quit all together now. While tach was acting funny I noticed the battery guage would show just over 12 volts when tach was not working and around 14v when tach was working. I did take the leads off the tach and cleaned everything up all nice and shiney and reassembled. No change still dead.

I need to bring the old girl home from the storage yard tonight to test the charging but, I'm fairly certain it is not charging. will confirm later.

I'm assuming all this means I need a rectifier. are they really $275?

Is it possible I have a bad connection somewhere? Ground maybe?

That motor probably has the water cooled voltage regulator. It is installed just behind the flywheel. Aftermarket units made by CDI are available for less $, and are excellent.

Do yourself a favor and check the continuity of the purple and grey wires between the tacho and the V/R first, to make sure it really is a bad V/R. Also, if you do not have the system check tach, you might like to get one. Make sure the wiring harness has the dual inline connector (8 pin?) for the system check tach.

Thanks Chris! can you tell where to find the engine electrical terminal strip?

Re: E200TXEO tach not working, no charge

Bruce, I am not sure what you are referring to.

What is the year on that motor?

1995 200hp.
I was trying to follow Joe Reeve's test proceedure. http://forums.iboats.com/showthread.php?t=190636

Re: E200TXEO tach not working, no charge

I do not know if the motor Joe was referring to is the same model as yours. Although the parts diagram for your motor lists a terminal strip, it appears to be a simple connector.

Your '95 is pretty close to the wiring on my '98. the VR also looks to be the same. The power pack is different, but troubleshooting the tach and VR should be the same. First establish that you have continuity between the grey wire at the tach and the grey wire at the VR. Disconnect it at both ends and make sure there is no continuity to ground. Do the same with the purple wire. You may need to disconnect the battery and turn the ignition switch on to make this test, since the ign switch might ground the purple wire. If they are both good, you can reconnect everything, and see if the tach and VR are working. Make sure you check all of the VR conections for corrosion.

Thanks! will do.

Re: E200TXEO tach not working, no charge

One more thing: while I'm under the power pack with the wires exposed, is there an easier way to check the stator other than the proceedures in the shop manual?

Re: E200TXEO tach not working, no charge

When you pull the powerpack up to get to the water cooled rectifier, you will see a large terminal strip where charging circuit and ignition connections are made. The back of the plastic frame that the powerpack is mounted in has a wiring color code sticker on it. It is very visible from the back of the motor if it is still there.
I would make sure all these connections are clean and tight.
It sorta sounds like your problem started occasionally and the progressively got worse...it was intermittent. To me, that is a loose or corroded wire, possible ground wire....
In general, the rectifier will not be intermittent like that. It will either be good or bad, because after all it is a solid state semiconductor device, not generally lending itself to intermittancies.

Re: E200TXEO tach not working, no charge

Thanks. I'll take another look. I lifted the power pack saturday and didn't see the sticker you mention or the terminal strip. It looked like all the connections were made with male and female round stacons with clear plastic covers over them.

Re: E200TXEO tach not working, no charge

Sorry, I am incorrect. I went and looked at the parts list for a 1995 200. All your connections appear to be made with male/female connectors of various styles. The rectifier connector, for example, has a large round (3/4" inch or so) two conductor male/female pair that has large yellow wires, right?

If so, there will not be a sticker or a large terminal strip. I thought 1996 was the year they changed away from the big terminal strip. Just looked at 1990, and it has the strip. That is the electrical terminal strip that Joe Reeves is referring to. You don't have it.

Same advice applies, though. Check the connectors for corrosion, signs of overheating. That yellow wire connector carries alot of current. Also, the single red wire that goes to the starter solenoid is the output of the rectifier and is the wire that feeds charging current to the battery. The gray wire is the tach signal. The purple wire is switched +12v.

Thanks! I appreciate the info. It'll probably be a few days before I can get back to it. Maybe even the weekend. I'll report back.

Re: E200TXEO tach not working, no charge

Didn't get as much done as I would have liked but, I did confirm continuity at both the grey and purple wires. neither is grounded. Lifted power pack enough to get to the connections underneath and did the continuity check on the two yellow stator wires as described in the shop manual. I got no reading at all on any scale between the wires and a dead short to ground on one of them. I'm assuming bad stator. I hope to pull the flywheel this afternoon. What do you use to hold that sucker still?

Re: E200TXEO tach not working, no charge

Sorry, Bruce...those stators are pricey. Your testing indicates an open stator.

I use a flywheel holding / turning tool that grips the teeth of the ring gear.

Maybe Advance Auto has one in their tool rental program...pay a deposit, use the tool...return it, and get your deposit back.

Re: E200TXEO tach not working, no charge

Pricey? BOY HOWDY! I just looked them up. Even the Sierra is $300 plus. Is the CDI as reliable as the BRP? How risky is a used one? can I check it the same way I checked mine?

Re: E200TXEO tach not working, no charge

I seem to hear that the stator is the weakest part in the ignition system.
It has a 35 amp charging coil, and if it was charging at 35 amps, 14.7 v to the battery, it would be running about 400 watts. Lots of heat there.
But that is not the real running stats...no way would it last long at that power level. IMHO.

I have a used stator. Just not sure if that is the best way for you to go.
Private message if you want to discuss it.

CDI stuff is good quality. I use them for all ignition parts.

Re: E200TXEO tach not working, no charge

OK got new stator and rectifier/regulator from CDI. I've got them both installed but, i have a problem matching up the wires from the charge coils to the 2 small amphenol connectors. Both sets of wires are the same color and each has one wire with a yellow stripe. this does not match with the other connectors one of which goes into the power pack and the other into the engine wiring harness. I'm stumped.....help please.

I would recommend that you contact CDI Electronics Support. Here's the link: http://cdielectronics.com/Default.aspx?tabid=65

Re: E200TXEO tach not working, no charge

Silly me. A couple plugs/wires were hiding from me. I took a break and looked it over again and it all made sense. I got it back together and it fired right up! Tach working now. Batteries being charged at 14v at 1000 rpms and higher. Took it to the lake and she is running like a top. Nice idle, great hole shot, gained a couple MPH top end speed. I'm a Very Happy man.

Thanks again for all your help guys.

Re: E200TXEO tach not working, no charge

Good news,
can I pester you to cut into the old regulator? I'm curious as to exactly what components are in there. Diodes obviously but I'm curious about what else makes it so pricey.
