Default Deltran Battery Tender Wireless Battery monitor 081-0172 no WiFi repair

Well, I have one of these Deltran Wireless Battery monitors that has no more more WiFi. Not sure what happened, but it died on my after I changed a battery on a generator.
This is a repair that addresses no WiFi, no blue LED, no Hotspot issue. However it still passes thru the charge to the battery and when hooked up backwards a red LED glows. That's it.

The case is easy to open up, no screws etc., just pry it by the sides. Once it is open the whole thing inside is covered in a see thru silicone of some sort. I was able to cut the silicon and pry it off with some pliers. On the side where the WiFi module sits, is a LM1117 3.3V regulator (Vin was shorted to GND). On the Vin line, there is a fuseable resistor (FUBAR in my case) and a SMD diode marked T5. The fuseable resistor I am guessing is around 20 Ohms or so and the diode is something equivalent to an FR102. Goodie! Swapped the bad parts and my Wireless battery monitor is working again!

Well, it is one of these boring repairs. I did it out of curiosity to see if the wifi module was actually bad or not. Btw. The wifi battery monitor is so far still working fine. Since my monitor is not outdoors, I didn’t bother putting that silicone crap back on.
