I'm back! With a problem!

Gold Member Username: OlegSanta Monica, CA USA Post Number: 1410 Registered: Nov-04 | I have this distribution block: http://www.knukonceptz.com/productDetail.cfm?prodID=KNF-12 About a month or 2 ago, I started noticing a burning smell when I turned up the volume and was able to trace it to the 4AWG output connectors on the block, they are getting VERY hot. Any idea why this would be happening? Thanks! |

Gold Member Username: CarguyPost Number: 6760 Registered: Nov-04 | Just how much power are you pulling via the D block? For a 4ga to get hot, you must be burning up lot of current. Do you have a partial short somewhere? Check for any loose strands or pos wire touching the car's ground/chassis. |

Alternator is only 180A, so i don't think it's supplying everything that everyone needs  I'm not aware of any shorts since everything, except that, appears to be working fine. |

Gold Member Username: Nd4spd18Northwest PA Post Number: 4513 Registered: Jul-06 | The maximum output of the alternator is irrelevant (not a limiting factor of how much current can flow through that wire) since the battery can discharge 500-1500 amps of current for a few seconds, depending on what battery it is. What gauge of wire is running from battery to D-block? If you've got 2 4 gauge wires coming out, you need to have 0 gauge going in. |

Also, check the wires with volume at zero, then at middle, then at the volume you were listening at. At each level, let it play for at least 5 minutes. If the heat only appears at high level, then you need to either upgrade to 2GA or get a more efficient amp. |

Gold Member Username: OlegSanta Monica, CA USA Post Number: 1413 Registered: Nov-04 | No, i don't know how to set the dmm for that. What reading am i looking for in a partially shorted power wire? Could it be something with the dist block? Should I try another? |

Gold Member Username: CarguyPost Number: 6765 Registered: Nov-04 | First disconnect all devices, then using dmm, measure the pos power wire. It should give you whatever the battery voltage is with engine off. If everything looks okay, then set the dmm to continuity testing. If you don't have that, then you can set it to low resistor setting. Now, disconnect the red power wire going into the Dblock. Use the dmm to test the 4GA power wire coming out of the Dblock. If you touch the pos and neg and get a reading, then there's a partial short somewhere. If you get zero, then no short. You have to make sure the power wire from the battery is DISCONNECTED before the above test. If not you will blow the dmm. |
