ok friends I am baffled!! I am trying to get my tach working I found the condenser unplugged and yam dealer says that has to be hooked up for tach to work. so I plug the condenser in and lights just dim right down!!! thinking condenser is shot I get a new one and the lights still dim. Anybody have any ideas!!! I reviewed the wiring diagram and all that condenser does is go brown wire to key ignition and black to ground. Could use a little info this.
Did you pull the harness back under the motor and see if its rubbed thru... very common problem.
