Parallel Ground Test Results
Hello Everyone,
Last week I ran a test with the SSG's charging battery ground connected to the power ground and noticed an improved charging effect. I ran some additional tests on the 7Ah battery and ~12.1v power supply and the results were encouraging.
Tests 1-8 were run with no rest period after charging. Tests 9-11
had a one hour rest after charging. Load is discharged through 50 ohm resistor down to 12.4v.
Observations :
So what's happening here? I would love to hear your thoughts and especially those of you with scopes try this test on your SG machines and see what you get.
Warm regards,
Mike

- Wheel speed was 17% slower and slower to rise
- Tuning the pot was very steady with little current bounce
- Using the LED strobe, there are two pulses per magnet (vs. three normally)
- Pulse on time appears to be delayed somewhat, exactly like the video Lee posted with an inductor in the trigger circuit.
- Output Current increased to 140mA vs. 80mA when connected normally
- Test #10 discharged to 12.38v
So what's happening here? I would love to hear your thoughts and especially those of you with scopes try this test on your SG machines and see what you get.
Warm regards,
