When I try to start my truck it wont do anything, no clicking nothing, the lights arent dim everything lights up. This has been going on for about 3 weeks sometimes it will start and sometimes it wont.
The “no clicking” is a symptom of, either a weak battery, or just one discharged. You can get the battery and alternator checked at many auto parts stores, free.
Would’nt my lights be dim though?
No, the lights are a very small load on the battery. The starter cranking is a large load, of 100 amps to 200amps, on the battery.
