Jinman, You have been very helpful, thank you so much.

I see the battery is 145.00
and it appears a special size, what do you use?

My G1800 has the battery in it that it had when I bought it. I'm not sure of the size, but by using a cross-reference online, I came up with a Rayovac SLI51R from Batteries+ for about $77. That looks like it might save you 1/2 the price. I also found the number 50B24L as a generic battery number. The original battery was 430 CCA and the Rayovac replacement is 450 CCA. You might be able to take the dimensions and CCA ratings down to a NAPA or other parts store and find a suitable replacement.

thought id see how much it was Too high from Kubota but i got one
for $52. at auto parts warehouse. Sure enough . STARTER now works
but shut off not working yet and gauges still not working. but at least
it starts... Thanks for all the information so far, but i aint done yet.

This happened to my G1800 at about 1500 hours, It was the combination box it was defective. After replacing it everything worked great.

Same problem as I have starts well if I link main starter feed to solenoid but bendix doesn't throw in on ign switch. I need a wiring diagram to se where voltage drop is. Can anyone upload one?

Welcome to TBN. You'll find a lot of info here if you learn to use the "Search" function at the top of the page. If you had done that, you'd find this post and a diagram already waiting for your perusal.

I was given a G1800 by a friend that needed some TLC. Recently, the fuel and temp gauges stopped working. My Kubota also has had a separate starter switch added since the starer position of the ignition does not work consistently. So, I decided to spray some electrical contact cleaner into the switch thinking that would help the starter position work. Not long after that the fuel and temp gauges stopped working. I just bought a new switch thinking that would help the starter position to work but that didn't help. Maybe it blew a fuse? SGARVER stated he replaced 3 fuses. I found 1 behind the screen under the dashboard. Where are the others?

Any help would be appreciated.
