A couple weeks ago I tried substituting my static gap with a SRSG with not so good results, safety gap fired as much as the main gap , and, took out a cap. This was after much adjusting,...my coil just didnt like it,....any ideas ??( My coil is powered by a single bushing 1.5kva pig with a homemaded gapped inductive ballast)
If you had a static gap previously, it may have been firing at a higher breakrate. If your new SRSG is 120 bps, you may have to set the safety gaps much wider than previously. Also the ballast may need to be set differently maybe.
