i fish my boat almost every weekend.....
had my motor, 07 zuke 250, going on 2 years now...
the 2 batteries i run jumped together, are probably a little over 3years old ..
went to the lake tonight for a little friday striper action after a long weeks work...

motor cranked fine but showed only about 12 to 13 volts , as opposed to the normal 14 it usually shows as i was idling away from the dock...
thought i might of left something on in the driveway that ran it down during the week and proceeded to get her up on plane...
volt meter started going nuts , swinging from 10 to 13 volts or so then the motor completley shut down.....oh crap.....
sat there a min then it fired right back up......
swung it back around to the dock and proceeded to undo all 4 battery cables and hit em with some sand paper since they had some minor corrosion on them...
turned the key over and it showed the normal 14 volts as usual....good deal.... lets go fishing.....
half a mile up the lake, same crap again....
limped back to the dock and tied up to try and sort some more stuff out....
the darn thing went from being able to fire back up at will, to absolutly nothing now when you turn the switch on.......it beeps like one weak beep then dead....
now when you hit the trim on the throttle it trims up or down for about 1 sec, the goes dead..............BUT WILL TRIM JUST FINE FROM THE TRIM SWITCH AT THE MOTOR....HMMMMMMM


just got home and put the primary battery on charge and its only showing like 50% charge........
this motor has started strong and fine for going on 2 years now and has always showed 14 volts on the suzuki volt meter...
it showed 13.8 on my furuno sounder tonight when it was wacking out????

can a pair of batterys that you use almost every weekend, go south that quick??

and if so, will it cause a zuke 250 to go nuts like it did on the volt meter, and completly fall on its face ,instead of just showing a gradual dropping of the volts over time??
tx for the help

Re: zuke df 250 wacky volt meter , need help

just bought and installed 2 new group 27 ,1000 cranking amp batteries and nothing changed.....
turn the key over, 4 red lights on the gauge come on faintly and beeps very weak for about 1 sec....
then dead as can be.....
next time same thing, but the darn motor will start normal as ever and run...

trim switch from the throttle will work in bursts then quit alltogether.....
trim switch at the motor will always work ......
volt meter will twitch when you turn the key over then lay dead below 10 volts now, even when the thing up and starts when it does......??
checked the white wire at the motor...bullet conn looks perfect and so do all other connections....
i keep the inside sprayed down and very rarely use it in saltwater....
couldnt find where the white wire is on the battery end....
checked all fuses, but if it was a fuse it would work or it wouldnt i would think.....not off and on like its doing.....
would a bad ignition switch cause all of the above???
tx for the help again.....

The white wire may be connected to the battery switch. It does have battery switch?

Check terminals at battery switch.
Check the connectors at engine and control panel.

connectors, connectors, connectors.
