Third voltage regulator on this unit. Purchased from Lowes in FEB of 2022.
At that time, I was not using a battery tender. Garage kept and would start it up and use around the yard and weekends at the hunt club property. While using in the yard, let it idle while collecting leaves, etc. while driving. unit cut off. Jumped started unit and recharged battery and checked for output voltage reading at battery. 12.3 and no change at 1k rpms. on 6/13/22 took unit to Authorized Dealer for 1st oil and filter change/ lube job along with possible Warranty Claim Work for a no charging issue. Dealer checked Battery which was, ok and replaced voltage regulator. (Listed action not part number on invoice ($140 for part). Dealer absorbed warranty claim cost until HISUN would pay the dealer. All was well.
10/19/22: previous weekend at the hunting property, the damn thing would not re-start......deep in the woods...... luckily, I had brought a battery source to jump if needed. This saved me. when back home ordered a regulator from eBay and replaced the faulty one that was the original one. Found this with additional investigating and pics taken prior to the dealer having the unit for the issue.
7/9/23: well seems the unit is need of another rectifier. Not charging the battery. had not been using a battery tender but will use it going forward. seems if the battery goes down the charging system will not bring it back, the charging system is there to maintain the battery voltage.
I usually do not run the stock light during the day and rarely use the unit at night. Did add a 32" LED light bar, but have it switched and have rarely used that up to now. When I replaced the second regulator and checked the voltage output, it was showing 14.0 volts at 1K RPMs and ran well. I am hoping the third one will be a charm and that using a batter tender will keep it all happy and work as intended.
