Hi I have 1992 C2500 Silverado 350,
I replaced the battery with a brand new one today, now when i turn the key it doesn’t turn over, just click / clunk which seems to be coming from the solenoid. When i turn the ignition on to the start position the battery gauge now climbs to just over 10 or 11 volts, previously it would be around 13 volts on starting.
Im guessing it may be the solenoid but the wiring on the solenoid does not match up to any wiring diagram i’ve seen.
When trying to trace the wiring I found the purple wire (in the second picture) was disconnected and could not see anything it could connect to
Im located in the UK so support for this truck is pretty nonexistent, so any help and advice would be much appreciated.
