G,Day everyone. question for the solar experts. santa gave a 80W fold out powertech zm9130 solar kit. When hooked up to 12.v aux battery in full sun volt meter was going from 12V to 13V rapidly. so I hooked up multi meter in series on 10 amp. and another multi meter paralel on volts. In part sun all good steady 2 amp and 13 v , Then in full sun amps are going from 0 to 4 and volts 12.5 to13.5 like a mad thing. I suspect the regulator is faulty. can anybody help with problem. many thanks in advance an have a safe year.

Lucky Macca but Santa may have overspent .. LOL
The reg is probably in FLOAT mode and will be pulsing microsecond bursts of low voltage high current at your battery - This is normal ..
If you need to
test it further then run a decent heavy load off the battery and see if the input steadies to 4 - 4.5 Amps .. Run an Airpump or 12V vacuum cleaner - something that uses about 10-15 Amps ...
I think you'll find it is working as it should ..
However if you need it tested and you're close by - bring it over ..
Cheers
Steve

Hate to say this but digital meters are useless on varying voltage. Use an analogue meter when dealing with varying voltages. You may find it is actualy going to 14V then droping back then upto 14V again & thats fine for that type of regulator. This will only happen when the battery is near fully charged.
