Welcome to the forum...

Was the cart charging before you replaced the battery and ignition switch? Hook a digital volt meter to the battery and run the cart at about half throttle and see what the voltage is.

battery checked at 13volts, when started and run at half throttle it remained steady at 13 volts. the battery was discharging before we replaced the battery and switch.

it could very well be the new switch,
i would get a wiring diagram and also take some time and map out the post on the switch

Do you all think that 13 is high enough on that motor???? Most of the 9hp motors charge up to 14 or so.

 

[HotRodCarts]

It should be around 14 volts. What are you thinking Radical, voltage regulator?

 

[samcudd]

we wondered about that, how do you check out a voltage regulator? thanks for your help!

The factory key switch is no longer available. This is the case with many ST parts. NAPA will have a suitable replacement in their Echlin line. The standard alternator is 20 amps. That is the standard for a Honda industrial engine. Add a snowplow, salt spreader, extra lights, and worst of all a cab heater, it just won't work. If loads are intermittent, try a larger battery. There was an optional alternator kit that provided 55 amps through a belt driven alternator. These parts were very hard for us to find.
