InterAv, PN- 015-01237 alternator and Hartzell R1224S-14 regulator. Thanks for your help

Under a light electrical load my M20F charges well (alternator, checked out 50 amp output, new voltage regulator, checked OK and replaced one new battery with another new battery, 12 volt system). Under a heavy electrical load the amp meter will cycle from neutral to large discharge at a regular two second cycle and it is not the strobe, l have isolated that and all other single sources as best l can. Any suggestions? Thanks, Jerry Beach

Amps fluctuating regularly every two seconds from small charge to large discharge. Volts stay between 12.3 and 13.5 under heavy load. Have a new battery and voltage regulator. I can hear it in my head sets. It acts like a very high amp strobe cycling, but l have shut the strobe off. Thanks, Jerry
