Have a no crank no lights /power situation on my 1994 C1500 ext cab 2WD;
Replaced battery and got 12.4v at posts; tested at power junction block using batt neg got 1V. Tested at starter solenoid (with solid clean ground) and my digital multimeter spun thru numbers like a slot machine in Vegas... (Im electrically impaired so not sure what that means) also tested at another two post block on the firewall on the drivers side (there's a black wire that runs from the power block post where the positive battery wire attaches to this small two block post) and again the multimeter kept flashing various numbers.
I removed the pos battery cable (both need replacing anyway) and tested them while connected to the battery (and nothing else) both cable to the solenoid and the power junction block leads read 12.4.
1. anyone have thoughts on what makes a multimeter flash numbers instead of giving good reads? (again ground was either battery itself or a clean solid surface)
2. anyone know what that small junction block on the driver side firewall is called?? (two post box.. one post at 12 the other at 6.. about 1 1/2" x 1 1/2" square bolted to the firewall with two self tapper type screws at the 3 and 9) see attached.. in the foto the top wire connected at the top post runs back to the power block post that also includes the wire from the pos battery cable far right post in second foto
Ill be replacing the cables regardless as said.. just wanted to know if I should replace the two blocks mentioned above.. or maybe the starter .. as I said the reading at the post was flashing number.. with cable removed (testing JUST the cable) was 12.4v..
confused
