| KonkeyKong:
there must be something whacky with the iso, I followed your directions to the "T", but no luck. The rest of the wiring that was left in the cab was awful so I'm not totally surprised. Now to find a simpler in-and-out iso.... |

But since you didn't bother testing it with a multimeter, you'll never know for sure. |

as pbj pointed out use a mulit meter and meter the leads it look's like a dual 117vac in which can confiqued as a 220vac in it is in the wiring..so start there also as was pointed out to u u have to confiqure the primanry side to take 117vac or 220vac best i can see is 1 to 8 and 5 2 to 6 and 3 which should confiquire it as a 117 vac input the easy test is remove all wires and measure between 8 and 6 low ohm's should read about 1-8 ohm's and 5 and 3 this will tell u the winding's same readings then for good measure chk between 1 and 2 .this should read open if this is the case ? then follow ^^^^^^ what i stated and u should be gold ed |

measured... check. 1 to 8 and 5...check 2 to 6 and 3...check plug it in...poof, blew fuse. added another picture of my set up to help clarify. Numbers in circles correspond to those on the schematic. |

try this 1 on the filter to 8 2 on the filter to 6 just that winding,and see if the fuse blows the winding ohm's is right if it dose not blow the fuse >>making sure there is 0 load on the secondary side<< u should find 120vac at 5 and 3 plus on the secondary side where u want to tie in... what u need to rember about these power transfomer is they are PHASE depented ie 0 to 0 /hot to hot any other config expect for jumping to 220vac will blow the fuse ed |
