Son decided to jump lawmower with van. van was running and decided to crank the lawnmower, when he tried to start the mower the van just died. Now the van will not crank, there is now power to the whole system. checked fuses and relays can't see any blown. Any help would be appreciated.

 

Check the cable to battery connections.

 

already did, van was running while trying to jump it and as soon as he turned the mower key to start it the van just died and no power now.

 

Did you test the battery for power?

 

Yes van was working fine until he turned the mower key and the van just died. Now there is no power at all to the key or dash etc..

 

Lol. What a pain in the ****.
There is probably a main fuse where the battery goes to the underhood fuse box.
Follow the battery positive cable to the fuse box and check there.
Its a 70amp fuse. Possibly.

Its a lawn mower. Should've not had the van running. Lol.

 

What year is your van? You have either a blown fuse link or master alternator fuse in the PDC.
