Closing out this post. It was the battery, though logically it shouldn't be since it cranks strong, has 12.2v without load and was trickle charged for days before installing. However i guess its a case of Occam's razor. I should have tried a different battery before heading down the...
Vout at B+ to ground is the same as the voltage at the headlights.
Vout at B+ to ground is NOT the same voltage as it is across the battery terminals (14.4ish vs 15.8) . (probably some load loss? / overcharging)
Ok. Stumped other than the fact I received a new, bad rectifier-regulator, which still seems highly unlikely but not sure what else there is.
From the service manual..
1 Test - battery charging for no battery charge (skipped). There's definitely charge happening
2) Remove R-R connector, test...
Transformer = The part with the wire leading to the spark plug. So I’d say the ignition coil. I assume that is an isolated circuit just for to fire the spark plug.
Its a new battery from the beginning of the season.
Just to clarify, I had no electrical issues until I had this hard starting...
Troy Bilt Super Bronco (2005) - 13AX60TG766. Will have to
The carb has a solenoid but no backfire specific one i know of - a) both from having my hands in every area of the mower and b) if I dont throttle down and wait 2 seconds before shutting off, it backfires something fierce.
I JUST put...
Hey y'all, I'm back with an update - and looking for more help.
It shouldn't be this complicated...
1) New Regulator-Rectifier in
2) Valve Lashing checked - they has a little too much gap, fixed.
Same problem with starting - couldn't get it to turn over.
Took out Cheap-China-Crap-Carb, put...
Thanks. Choke is closing, had the filter box off while troubleshooting. New carb came pre-adjusted and worked fine for most of the season but that's on my to-check list once I solve the electrical gremlin.
Model is a SV590. Thanks for offering, I actually have the service manual and just noticed the very good section on testing the electrical. I will pursue that later today or tomorrow. I'm assuming its the Rectifier-Regulator without testing, so I already ordered a new one & a 20A blade...
Brief history. 2004 Troy-bilt Super Bronco Kohler Courage 19 Engine. VERY well taken care of, but still had my share of issues. I've always been fairly capable, well read and methodical in all I do but I'm not an expert. Worked out good for me so far.
2 seasons ago - Rebuilt transaxle...
