Hi All, B&S. Vangard , battery drains over night, 2.29 Amps of parasitic voltage, after much TS. I removed the positive lead to the alternator which cleared up that load, alternator is putting out 13.5 VDC , replaced the Regulator/Rectifier with one from another engine, same results, I should mention that the engine runs on for about 5 seconds +- after the ignition switch is turned off, it runs a hydraulic pump so no blades etc. are still spinning.
Any thoughts?

Which of the 1000 different Vanguard engines do you have. model number would help us a lot. that way we can see what engine you have to give more directed advice.
I'd be suspecting the ignition switch. Be like leaving the switch in the "on" position when it's turned off.

The engine running for 5 or so extra seconds means that the keyswitch/kill circuit isn't working, as it is shut down by the fuel solenoid. So your problem may be related to that problem {the keyswitch area}

Have you recently replaced the keyswitch? Is there any corrosion on the keyswitch?

Hi Guys, just a update on this problem, engine run on was due to the fact the ground connection to the coils was broken off , repaired and all is well, anti backfire solenoid is working, as stated previously this engine is running a hydraulic pump that drives a small locomotive, the alternator on the B&S , regulator/ rectifier, are functioning fine, there is an additional 1 wire alternator in parallel to provide more power to drive the other accessories.
yesterday I had the new battery load tested,OK , installed the fully charged battery retested for any current leak and all was fine, will see how things go this AM.
Glad you found the problem, but I'm confused. How does a broken ground to (is it both coils?) cause a parasite draw? Why did the engine run on for 5 seconds and then stop? A broken ground would keep it from shutting off completely. Wouldn't it?
