fuel guage + other problems

[kopy kat]

the fuel guage on my '99 SeaRay 210 BR quit working, so I had the local shop pull the sending unit with the idea of replacing it--they checked it out once it was out of the tank and said that it worked fine-sent the right message to the gauge, etc.---now it's not working again and neither are the blower, bildge pump, lights--whatever is controlled by the unitized switch assembly that SeaRay has in the dash. I've checked all fuses in the fuse compartment and they all check out ok--any ideas as to where to check next would be appreciated---thanks, Larry

At this point you need a voltmeter. Check to see if you have 12 volts to switch, then if you have 12 volts coming out of the switch. Make sure you have a good ground when you measure.<br /><br />A quick guess says you have a bad switch

Another quick guess is that there is an intermittent connection in the circuit feeding the devices that don't work.
