Cub 154 low boy

Was mowing with the cub when it just died. Turns out the positive battery cable was rubbing against the clutch, shorted out and tore in two. Now the charging rate is erratic. The starter and generator are one unit. Is there anything special about the voltage regulator on these? Thanks.

You do need to use the voltage regulator for the starter generator.There are lots of regulators that look the same,but won't work.Sounds like something fried when it shorted.There is a testing procedure to follow,and can isolate the problem components.Get the book and follow the steps.Weak points in those are the ammeters and ignition switches.I put a wiring harness in one for somebody last winter,he always had erratic charging and running problems.All his terminals were a little crusty,so he just went for the new harness.It ended 25 years of fighting with it.

Hamilton Bob's has the correct parts.

I forgot to mention that.I go there first,and if they don't carry or make it they are happy to tell you who does carry it.I did some work on one I've been tinkering on since 1976,and had to buy a new driveshaft.There is a long and a short,and they didn't carry the one I needed.They sent me to the guy that did have them.Best thing I got from Hamilton Bobs was a set of brackets to hold the steering box.Factory design was very,very poor and weak,so they sell a nice set to use in addition to the originals.Weld them in and no more flex in the steering while whipping the wheel around when mowing.In the last clutch kit I got for this one the new throwout bearing made crunchy noises while spinning it with my fingers.The owner bought the parts himself,so he took it and was going to talk to them about it.
