Help!
I have an old natural gas engine that I have designed a Capacitor Discharge Ignition module for. The module uses a pre-made boost circuit that takes 12vDC from a truck battery / solar cell and boosts it to 350vDC that I then route to my ignition circuit. This worked great on the bench where I used a plug in transformer 120vac to 12vDC that was rated at 0.1 Amps. When I hooked it to the battery I let the smoke out.
So I then clipped on an inverter, plugged my power supply in and everything worked great. This is NOT the way to do this. Can you please help me to make a 12vDC Source that controls the amperage available from the battery? I want something that won’t just drain the battery when not in use. I have a manual switch to turn on the 12vDC now so I could use that to kill power when not running but I also have a remote off switch that shuts off the gas valve. If the device keeps draining power that’s no good. I can use an interposing relay but I’d love to eventually love a more eloquent way to shut it off. Right now I’d settle for not roasting my boost circuit or using an inverter.
Thanks in advance.
