| Wiring Pac Drive Problem. LED runs hot (SOLVED: Don't cut out inline resistor) |

The two lights that are shown in the dark photograph are both from GGG. The one that is dimmer on the right of the photo is the first of two in a series of three. This first one also runs extremely hot. Starts to get hot within 30 seconds of the computer starting up. This is the second one I have installed due to the last one burning out within one day of use. The last one, from Paradise, is dull. I'm not worried about that one. It is in the back of the cabinet. My concern is that the first two, both from GGG are not the same intensity and the first one in the chain is EXTREMELY HOT and burns out. It starts fine but gets hot and burns out. |

Sounds like there is a poor/high resistance connection in the first button. Try swapping the bulbs in the CDRs to see if it follows the bulb or if it is related to the socket. Scott |

It may be. When GGG sends out their CDR's they solder on the wires. Why? I don't know. I had to remove the solder so the connection may be bad. I have two new push buttons coming from Ultimarc that I am going to switch out with these. So they will be same and not have solder still on them. I went to get a desolder tool from R*AHEM* Shacmffmfmf yesterday. Convinced myself that I would only need the desolder wick. :banghead: Might have over heated the post trying to remove the solder. Need to go with my gut in the future. When I get home I am going to try to put the grounds in order of the buttons, do what you requested, and switch buttons. Here's to hoping. |

Yeah, you might have created the problem during the desoldering. If it's any consolation, you're a little less likely to cause heat damage using the wick than with a solder sucker. Consider getting a heat sink clip, too. Scott |

This is why the LED's are getting hot, and burning out. The wires can be shortened, but the section with heat-shrink material, near the button, must remain. |
