OK, I am know far and wide for trying to save money. Over the past several years I have been using a pressure switch from NAPA to replace the back-up light switch on these older Allison transmissions. The price for OEM is over $100 and the NAPA switch is like 8 bucks. Anyway, this go around I put the switch in and it toasted my breaker (not sure if my breaker wasn't already toast, but that is a side issue). I put a fuse in place of the breaker and got another switch and, pow, it does it again (all I have to do is turn the key on and the fuse blows). If I unplug the switch and jump the wires the lights come on and the fuse doesn't blow. Any ideas? Or am I just going to have to put a hundred dollar switch on this one? |

OK, now it has changed. It was coming on when I connected the wires together at switch but now even when the switch harness is disconnected I am still getting a direct short. So, does the wire run from the fuse box through a body connector junction and then down to the switch? This is on a 1998 Chevy/ BB |

Man, I hate chasing electrical problems. Especially when it turns out to be simple. lol I found a wired shorted to ground at the bell housing. This is after it goes through a connector. Had to take the dog house off to get to it. I didn't see it until I turned over the pack of wires. Was thinking about just deleting this post all together but I will leave it up hoping it will help others. If you read this and it helps you please post so I will know my efforts to post were not in vein. lol |

We feel your pain. I vote you leave it up and give us the NAPA number for the $8.00 switch. |
Why yes, the ORIGinal CHARGER is a Fastback |

granted it's not $8.70, but I only pay $28.35 for an Allison Reverse Light Switch pt # 416372C1 from International (it has gone up severely the last couple of years.)
over $100? I'd be talking to my sales rep about a different pricing scale... and in the meantime, I'm going to check out Napa, lol

Bryan I used that same part # switch on the generator in the wanderlodge. All this time I did not think about it working on the allisons. Way to go man. |

That switch also works as a air door/8-way activator in the older Thomas ER's |

Is that the one with the pig tail on it? Maybe they have come down over the past few years. I think it was 8 or 10 years ago when I checked on it at Allison last. I try to check those things out more often but when you have a NAPA right across the street it is hard not to just go with what works and forget about OEM. |

The one you have pictured is the older version ( I assume it has round connectors inside the boot). The OEM switch on mine have a pigtail made right to the switch. What I do is cut the pigtail from the old one and install female spade connectors to the cut ends and plug them into the above NAPA part number. |
