Post subject:  battery not charging on 618

The battery on my 618 tracstar machine is not charging. When machine is off battery voltage is 12.1 volts. When running it is 11.7 volts and dropping. While running I measured the voltage at the dynamo with the plug disconnected. It was 37.8 volts AC. Does anyone know of a wiring diagram for this machine? Is the proper voltage from the dynamo supposed to be 24 to 28 volts AC? Will I need to replace the dynamo and or rectifier?

Here is a similar question that may help:

I think the voltage output of the dyno is 19-23 VAC. The voltage output of the regulator I think should be 14 VDC or so being supplied to the battery.

Here is our current T618 wiring diagram: ... =ST1800701

If you have an older machine it will be similar but it's always a good idea to punch in your serial number just to be sure.
