Well, I'm not so sure that it was just a dry battery. After driving for 200 miles or so with the last 25 with headlights on, the truck wouldn't start after stopping. We pushed it and it started fine, ran fine, but under load the battery and brake dash lights came on. I turned on the headlights (it was dark) and the red dash lights no longer lit up. They would illuminate if the headlights were turned off. We drove for 30 more miles, with no dimming of the headlights- so doesn't sound like an alternator or battery. While coasting I turned off the engine then tried to slip the clutch and start it again but the dash was black and no start. Walked home and towed it back and have the charger hooked up, but the battery is nearly fully charged. Could this be the ignition switch?
Thanks
