no power in cab.

ok so my 85 k30 6.2 was turning over fine.(new ip was bleeding it out) then i hit the key and lost every thing. i have power to the fuse box but nothing anywhere else. i split the box and see no wires pulled and i even checked the power coming in and i have 12.68 just like i should but still nothing in the cab works. headlights are the only thing. she wont crank over no glow plugs wtf?? help!!

Re: no power in cab.

Do you have power at the junction block on firewall beside the brake booster? There is a fusable link from starter to that block that powers the cab if I remember correctly??

Re: no power in cab.

I believe so...I am trying to think what else to check & drawing a blank now.Pretty sure that is the only power feed into the cab,but someone else should be able to clarify it.

Re: no power in cab.

I'm thinking by the sounds of it perhaps your ignition switch took a crap..... I think the best way is to check for keyed power at the fuse box with key on.... perhaps that's the issue
