1. Yes 2. Yes 3. You must replace the solenoid w/ the same make and model. They aren't generic.

***"not necessary to disconnect both cables when working on electrical, just the negative/black?"*** That is correct.....So long as the negative/black cable is in fact, the GROUND cable for the vehicle electrical system. And in most machines built in the last 40 years or so, the negative/black is the ground conductor. But you must "cling to" every word of the description. "Negative", "Black", "Ground"! Each word must be considered as a separate and individual criterion when you are preparing to "put a tool" to the battery terminals. (this is a lesson, listen up) There are currently (no pun) no laws governing the colors of wires and cables used in AUTOMOTIVE applications. There are "generally accepted and recognized practices", but no REGULATIONS. Black is nearly universally used as the color (by OEMs) of the negative battery cable, Red for positive cable, but some OEMs might decide to use black cables for BOTH positive and negative conductors leading from the battery posts. And, additionally, you must always consider that the original RED positive cable.....might have been replaced with a BLACK cable. Furthermore, the OEM, BLACK negative cable, might have been replaced with a RED one (you see all kinds of things in "used equipment". The odds of finding a BLACK cable for the positive conductor are actually pretty good, while the odds for finding a RED cable for the negative conductor are slim (but I have found them more than once). Nonetheless, since it only requires that you "look at" the markings on the battery (positive+, negative-), that is what you MUST DO,.... each and every time you prepare to "put a tool" on a battery terminal. ALSO, when you identify the negative post/cable of the battery......trace the cable to where it connects next. If the negative cable connects to the vehicle frame, chassis, or engine block....it is the GROUND conductor. This configuration is what you will find on just about every machine/vehicle of recent manufacture. But, it makes sense to understand the relationship of "color vs. polarity vs. function" in a vehicle electrical system. IF the black cable is connected to the negative battery post at one end, and to the "vehicle ground" at the other end.........that is the only cable you need to remove from the battery in order to render the electrical system "inert" and safe to work on. Even that statement will have "limitations" if the vehicle has advanced electronics and engine/cab controls, but for MOST L&G tractors, it is the best, safest, practice. ................................................... Getting back to your Huskee. Before doing the next test, disconnect the GROUND cable from the battery. Leave all wires connected to the solenoid "posts",.... connected for the test. The black/blue pair will be removed but reconnected in this procedure. To further test whether the solenoid is defective (shorting inside the solenoid), if the first series of tests point in that direction, remove the mounting bolts of the solenoid (where solenoid mtg bracket fastens to chassis/frame. Reconnect the black/blue pair of wires to their same chassis/frame bolt and secure with nut. Use some kind of non-metallic, electrically insulating material (suitable piece of cardboard, carpet, even an old sneaker will do) to set the solenoid on so it can't touch a grounded surface (chassis). Once you have the solenoid resting on the non-metallic material, reconnect the ground cable to the battery negative post. Now, operate the ignition switch to the start position. If the fuse does not "blow" now, it indicates the solenoid has an internal short to ground (fuse DID NOT blow because no ground was provided for the "short" to use). Don't expect the solenoid to operate during the test. Access to the solenoid on my Huskee is somewhat "difficult at best", but I find I can get a better view of it by going in from the right side floorboard/step area (front end of center console and backside of engine). I have to lock the brake/clutch pedal down to get more room for my head. In taking the photos, I went through the battery access under seat AND from the other end I described above.

We just paid $192 to find that the wire in the condensing unit was vibrating and caused a short by wearing the wire insulation cover and as it hit the copper tubing our unit would blow the inside air handler fuse when we turned on the unit. First the thermostat needed batteries, then we were unable to get the unit to blow heat because of fuse blowing. I find it really unbelievable that install did not wrap wires with at least electrical tape ( now shrink tape is used) and zip tie wires together so this issue did not occur. The unit will be 10 years old in 6 months. The wire in question had a small dot of a wear hole. Repair of this issue was to cut the wire and use a wire connector. We used electrical tape on all wires that have possibility of hitting any of the components and zip locked wires together also to keep secure off components, i.e. copper tubing. Hope this helps DYI.

Has anyone run into this problem? My board keeps blowing the 3 amp fuse on the main board and I'm not sure why it would do that. I can't find anything about it on the web or in the books.
