periodically maybe once a month the truck does not start. acts like battery is dead. (battery is new) no lights or dash or power locks etc. work. attach battery charger and truck starts. most times it starts ok. any one have an issue like this? any suggestions as to where to begin looking?
Sounds like you have a parasitic drain. That is when something, a light, one of the computers, ect, stays on after the key is removed. There is a way to check that but it involves a digital voltmeter and based on your post, I’d guess you don’t own one. Good independent mechanics can find the drain and fix it. Be prepared to pay for his diagnostic time. Good Luck
