06 elantra battery died when dome light was left on. No jump box, cables, or charger around so took battery from late 70s early 80s ford pickup hooked up to mine started no problem then removed truck battery and connected mine while running. Now no dash lights blinkers all blink fast now front and rear. No power windows no radio no brake lights no rear running lights. Highs and lows r fine dome and map lights fine reverse lights good PRND321 on dash light up but no speedo or tach lights. Did i fry half my shit? Fry as in irreparable? Also i was taking fuse box out under hood to check for some kind of burn halo mark underneath and the ratchet touched both terminals baaahaha… WAM! felt great. Although nothing seemed to happen from that just figured id put it out there.
