Hi, im new here. I have a question, I recently got a yamaha fz1 2005. I jumped the thermostat radiator cables in order to have the fan always on, I did the same on a sv650 2000, but this time did not get the expected result, after that, no more rpm reading, the needle was dead. I after discovered that the problem was the water pump, so maybe the thermostat was ok. I did not get the fan on, why? I removed the jump and ended wiring the fan just directly to the battery, using a switch, after that the electrics seems ok, just the speedometer that won't turn on. Does anybody know what exactly happened? I checked the fuses and seemed ok. thanks.
