no crank, no power

[last254]

Okay so my problem started when I left my truck sitting for quite some time and when I tried to start it I found my battery was beyond gone, and the cables had corroded extensively. So I bought a new battery and cleaned up the cables quickly and started right up. A week later I try to start it and I got nothing, no crank, no fuel pump sound, and even more interesting no headlights (and yes new battery is good). I know these headlights are separate so I am thinking either multiple fusible links or starter relay? Also I have done Cruiser's ground refreshing tips in the past and also double checked the battery ground and dipstick ground this week. So what do you guys think? start with fusible links and starter relay in the morning?

 

Also how do I test fusible links? backprobe with multimeter and test resistance?

 

How can I test the starter relay as well?

 

I am referring to the diagram here in this thread for the starter relay btw http://comancheclub.com/topic/49932-battery-short-to-ground-now-truck-won't-start/?hl=starter+relay&do=findComment&comment=508394

 

 

Thanks for any help you can provide

With a meter , check for voltage at the POS terminal of the battery. Then, go to the large nut/stud on the relay. Power there? 

 

If so, probe  the spade terminals of the relay. 

 

Also check for voltage at the starter cable.

Thanks for your help Cruiser! I checked  the starter relay and found a burnt out wire, replaced and good to go
