Thanks retro and AKATV, that will be very helpful. I'll let you know how I get on

Same ATV over here... your shorted zener replacement should be 5.0 volts to drive the speed sensor. Have fun!

Thanks retro. Do you know what type of output the sensor has? 

I've been looking at the 2000 - 2003 Trx350 Rancher service manual and it says to check the loom connector for battery voltage. Don't know if that's the best manual to look at.

The speedometer puts ~5 volts on the signal wire, is that the voltage your talking about?

It's a 2000 Honda Fortrax 350. I'm in the UK, don't know what the US equivalent is.

Hi all

I need help identifying a component on this PCB. It's a zener diode (ZD4 next to the connector on the left) that I think is used to regulate voltage to the speed sensor. It has gone short circuit. Does anybody know the zener voltage?
