Yamaha 1999 GP760 WaveRunner Problem

[Matrix_110]

I just purchased this 99 Gp760 and it was starting and running great yesterday. The guy I bought it from started it at least five times just to show me how. Then he wanted to remove his trickle charge plug so he had to remove both wires from Battery then he put the leads back on and I tightened them after making sure red was pos, blk was neg. He went on his way and I went out this morning to show it to a guy and it will not even try to start! I first put the start wrist clip under the button then turned on the fuel, pulled out the choke, hit the green start button while applying a little throttle and NOTHING! I put a meter on the batt and it was 12.8volts and did not drop any when the start button was pressed. I found the fuse and it checked good. I get no display info on either LCD meter when key is on or when start is pressed. The only display I get is when I press the left button on the panel the right meter displays CODE and when you press the right buttons it will display A, B or C! Other than that it is as dead as a rock! I would sure appreciate any Ideas you may have. How it could have went from everything working perfectly to nothing works over night when just a battery disconnect was done is beyond me.

look for a small ground wire or positive wire that he forgot to reconect when he fooled with the battery.

It may be in the locked mode after the power was interrupted.

Press the mode button on the left side and when it says code, press A four times. It will then say START. Try to start it..

When you disconnect the power, I believe it reverts to the lock position. The four A's are the default code. If it has a saved code and will not unlock, post that and I will give you the procedure..

If it says LOCK do it again and will unlock it..
