Diode Assembly - 1863
Hello all!
I was wondering if anyone happens to have the specs for the diode used in the diode assembly for the 1863. Looks like a short stubby Schottky diode with connectors at both ends and covered in clear heat shrink. Specs would be great, but if you happen to have a diode on your rig could you either take a picture or write down the numbers/letters denoting what model it might be? My unit has some goofy jury-rigged set up...red wire that looks to be between the starter solenoid and fuse has been split and 1/4" female connectors added. A mini ATM sized diode has been connected between both female quick connects. No specs on this little diode but assuming 400V 1A. This diode popped spectacularly and I'm trying to get it to a point where it is reliable. The fuse between the starter and key switch was a burned out 5A (ATC style) fuse...I replaced it with a 20A fuse as suggested and the little diodes are popping. I'm assuming I need a more suitable diode (rating lower voltage, higher amps), hence I'm trying to figure out what was used by CC. I'm cheap and really don't want to pay $30 for a NOS when diodes are just pennies. Any help and directions would be greatly appreciated!

Those only send power to the fuel solenoid on the carb and 1 amp should be plenty. Either your fuel solenoid is shorted or you have that circuit feeding something else.

Update...
Thanks to Oak, I refocused on the electrical issues I was having. Turns out I was chasing a couple of problems that weren't related and my mind tried to make sense of it as a whole rather than working one issue at a time. The diode issues was unrelated to the fuse...duh. went through the fuse holder to tighten the prongs. Loose fit = intermittent power. Cleaned things up and added dielectric grease. Fired up without issue...and without the diode in place. Got too late to try it with the diode...looking at the schematic, I may have had it backwards. Showed me that my memory is crap, and having a printed diagram on hand keeps me from being an idiot. Will try the diode out tomorrow. I believe my next step will be to disconnect all electrical connections, clean them up, and reconnect with dielectric grease. After all, I'm pretty sure most connectors haven't been cleaned, let alone inspected for 30 years. Thanks!

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
