I have a 1720 cadet. I cannot find the 20 amp fuse. Any ideas. Also how do I get into the dash board? TJ

Fuse for what?

The fuse is in the inline fuse holder on the red wire leading to the ammeter from the starter solenoid. This is the service manual for those machines, it might help.

Tom - Welcome to the forum!

Dave, I think there's only one fuse on that tractor, so Steve has him headed in the right direction. Maybe let the guy get a few posts in with us before we slap him around like we do each other! :lol:

This tractor is one that I have just purchased. Some changes have been made to the electric system. I need to jump the starter solenoid to get it to crank. I was looking for the fuse and still cannot locate it. Is is under the seat or in the dash board. Does the gas tank need to come out to get to the dashboard ? Any advice would be appreciated. Thanks. TJ

Tom, It may have been removed if someone rewired the tractor. It is supposed to be in the line that goes to the starter from the meter. The battery positive cable connects to the same post. The idea is that all the power that the charging system puts out goes through the fuse. But if people add things or there is an issue with the wiring they might remove it because the fuse keeps blowing, instead of correcting the problem.

The dash isn't that easy to remove. The plastic panel matches the metal panel under it, the gauges, controls and switches go through both pieces. They all have to be removed to get that panel off. If you mean the entire dash tower all the above get removed and then you can remove the tower.
That is in that book as well.

You couldn't do that under any circumstances. Dag wouldn't believe it was you anyway..

He did post back... I tried to be funny so he'd see we were semi-friendly...

Dave - Ha! Yes, "semi-friendly" is about all I can agree to, anything else is just too syrupy sweet and mushy!

BM - No need to be nice to dag, he really wouldn't know what to do with it!

TomJ - It's probably time to start working backwards with a multi-meter looking for where you lose voltage. The problem might not even be the fuse. The manual will have the schematic. Start at the starter solenoid and work your way backwards checking for voltage at each connection. It can be a bit tedious following the wires through the harness, but the color should stay the same until it the next connection. In doing this, you will likely find the problem and the fuse.

Mind reading software ? Gone for a while and they upgrade the site . I don’t know what that software costs but for a few guys they’d be overpaying even if it was cheap . You have to have something upstairs to read , myself included . :D

Well I like the idea of following the wires. I have purchased the service manual so that should help. It is a shame someone has been fooling with the wires. Thank you to all who replied.

I take it you couldn't download the service manual I uploaded in my post? That is the one for that tractor. I see wiring butchered on them all the time, don't think I have bought one yet that wasn't modified. That said I built a new harness for one of my supers with added relays, fuses and ground wiring plus eliminated some of the extra switches. The extra parts will clear up some of the common electrical issues from rust and corrosion that are common on these machines as they age.

I'd overpay for that software myself!

It would help getting along with all the women in my family!!!!

Jess, nice to see you stopping by!

TomJ - Pay particular attention to the condition of connections. Apply dielectric grease to every connector before putting them back together. Also, the key switches are a known trouble spot, so make sure that hasn't become your "open fuse". The backs of the key switches will be burned when they're going bad. Tedious work, but there's nothing impossible about it. Good Luck!
