Hisun Sector 550C total electrical failure.

[todd93]

Hi, all! I. I'm new to the board, hoping someone could help me out! I have a 2020 Hisun Sector 550C that I bought new in 2021. Today, I took some stuff next door to my parents. When I went to leave, I turned on the key, heard the solenoid click, but no lights, no guage activity, no fuel pump, and no starter. 

 

The battery is good, I checked all the fuses, they are good. Not sure if the relays are good, or even what to look for there. Is it possible that it's maybe a wire? 

I'm really stumped on this one! Any help would be deeply appreciated! Attached is a pic of the fuse box layout. 

 

Thanks!

Just a quick update, I believe the problem is the main relay. This is not a serviceable part. It's not the small box with some fuses that some models have, it's one small relay plugged into a wiring harness. Weird thing, I happened to be walking by it, turned the key, and it magically worked! At least I was able to get it back home!

Relay sticking? Any corrosion visible? If it does it again give it a sharp tap with the bandle of a screwdriver and see if it resolves temporary.

Most relay failures I've seen are due to arcing on the contacts or corrosion from water getting inside. They're not well sealed.

Yes, I can understand that, and yes, I did tap the main relay quite a bit, it's quite different from normal relays... Honestly, I can get the cover off of a normal relay and visually inspect it... I'll share a pic of it, I ordered one off of Amazon, waited for it to fail again, replaced it, and no more trouble!

There are probably more than one set of contacts. Glad you got it all sorted.
