The vehicle won't start, dead as can be. Acts like a dead battery but.....jump starting does nothing. Here are the symptoms:
Headlights (but tail lights do work)
Guages & warning indicators
Dash display lights
KC lights (wired through a relay to the battery). I left these on for a few minutes and they burn bright, no dimming.
Batery is a 6-month old DieHard Platinum. Checked cable connections, corrosion, etc. All is clean and tight.
Vehicle has a viper alarm with remote start. Never use it. I talked to two viper installers. Both said if the alarm was causing the issue, I would still have headlights.
