K5 blazer electrical issues.

[Trip Wire]

Picked up an old K5 that has not ran in prob 10 years. just installed a fresh 6.2 and did the 12V conversion. The problem Im having is that I have no power at the fuse block....just 2 ports have any power at all. zero power for headlights, starter and injection pump. could wiring the glow plug relay in the wrong way be the culprit or is there something deeper I should be investigating?

Thanks in advance.

Welcome aboard.
Start here and double check your 12V conversion wiring.

Just repaired this same issue on a customers truck. The fusible link between the 12v junction block on the firewall and the battery was blown. Run a temporary jumper wire and see if that fixes it.

Or check it with a digital multi-meter.
