96 gtx problems

Re: 96 gtx problems

i removed the 15 amp fuse to bypass the rectifier no diffrence

Re: 96 gtx problems

That is not the same as testing the charging system. When a rectifier goes bad it creates electronic noise that screws up the CDI, making the ignition spark erratically.

Re: 96 gtx problems

ok, but if it is out of the circuit you would see some improvement

Re: 96 gtx problems

Without removing the wires connecting it to the stator and the mpem, I cannot see how it is out of the circuit. You only disconnected the charging wire to the battery by removing the fuse. That is why no manual will ever suggest you do such a thing to find out if the rectifier is good or bad.

In less time than it takes to open the electrical box and remove the fuse, you can read a multimeter connected to the battery with the engine reved up to 5500 rpm. If it is not in the mid 13 to mid 14 volt range, your rectifier ( or stator) is not working correctly to charge the battery.
If the rectifier is bad, the engine will run very erratically. Eliminate that possibility by testing it. Otherwise you may be here for days trying to figure out why your motor isn't reacting to carb/fuel fixes.

Re: 96 gtx problems

i will check it and let you know thanks

Re: 96 gtx problems

checked battery voltage 13.1 volts crank drops to 11.8 running 13.7 volts

Re: 96 gtx problems

That sounds good to me. Your stator and rectifier are working properly and charges the battery as it should.

Now remove the carbs and pressure test those needles and seats to see if they are leaking.

Re: 96 gtx problems

removed carbs and found problem with one gasket replaced and refitted. now runs fine on trailer responds with no hesitation. put in water no hesitation but will not rev over 3500rpm under load. i bypassed the fuel selector no change

Re: 96 gtx problems

On my 96 GTX I had a problem like this that it would not rev past 3500 in the water. I had to turn the red caps in on the rave valves and that solved my problem. I only had to turn them in about 1 turn they had loosened up so that they were flush with the black cover.

Re: 96 gtx problems

Dave, I hate to burst your bubble, but even if the rave valves were cemented into the clyinders, it would rev up to about 6000 rpm. I do not know what you did to fix your motor, but turning the red caps on the raves would not have made your motor go from 3500 to 6700+ rpm.

Re: 96 gtx problems

Reece,
Did you pressure test the carbs? Did you open them and see if anything was not right in there?

Re: 96 gtx problems

Bill I understand what you are saying but my ski wouldnt rev up past 3500 rpm and i looked at my budys 97 gtx and his red caps were in more than mine so I cranked mine in to about where his were and I tried the ske again and it would rev up and go. Dont ask me it just cleared up and went. Maybe it was the rectifier. Just thought I would through it out there.
