no everything checks out( fuses , wiring) worked when i first installed it. then i thought my stinger voltage gage took a sh*t at 1st until i started checking it with a volt meter then hooked up my battery charger and batteries where @ 49% voltage never went above 12.8 volts turned on lights ,amp heater ect.then down to 12.2 volts , im just frustrated like i said had for 2 weeks but truck is under construction so has maybe 1/2hr usage on it but i put the old 10si back on there works great but with a 90 amp alt cant jam lol
