if nothing else works or you cant be ****ed, violence will will solve the problem... will get it tested when i go to mechanics next
Check the "earths" ... run a temp earth directly to the engine from the battery to see if you have a earth problem. Happened to me and I hadn't touched anything ... found the main earth to the body had corroded???
charging info for optima yellow top Recommended Charging Information: Alternator: 13.65 to 15.0 volts Battery Charger (Constant Voltage): 13.8 to 15.0 volts; 10 amps maximum; 6-12 hours approximate Float Charge: 13.2 to 13.8 volts; 1 amp maximum (indefinite time at lower voltages) Rapid Recharge: (Constant voltage charger) Maximum voltage 15.6 volts. No current limit as long as battery temperature remains below 125°F (51.7°C). Charge until current drops below 1 amp. Cyclic or Series String Applications: 14.7 volts. No current limit as long as battery temperature remains below 125°F (51.7°C). When current falls below 1 amp, finish with 2 amp constant current for 1 hour. All limits must be strictly adhered to. Recharge Time: (example assuming 100% discharge - 10.5 volts)
should be running more then one earth!!!, should pigged back a few more earths on there with at least 4awg to 0awg wire
Could be the starter motor solenoid? If it happens again try throwing the hammer at the starter instead.
