| 776316 | 2009-06-09 03:09:00 | Finally got time to look at the radio. After wasting most of the afternoon trying to get the radio out by removing the trim I found it just clips in. Behind the radio there was indeed a yellow wire but it wasnt connected to anything, instead a pink wire labelled continuous power was connect through a 5Ma wire fuse. This fuse was blown. A new fuse fixed the problem. Thanks to all. The yellow wire typically goes to a power antenna or a soft switch for a power amplifier. That being as above - the other (unknown in Upsidedown Land) pink wire is for the KAM - as I stated. |

| 776320 | 2009-06-10 06:34:00 | I think it was actually 500mA | tut (12033) | ||
| 776321 | 2009-06-11 10:26:00 | The memory wire usually needs only a 1 or 2 amp fuse. Fuses blow for a variety of reasons, old age being one. If it blows again, I'd suspect the head unit | Phil B (648) | ||

Fuses should be sized and located to protect the wire they are connected to. If a device like your car radio suddenly draws enough current to blow the fuse, the radio is probably already toast. The fuse is there to protect the wire, which would be much harder to replace than the radio." There's no auto wiring that would need 5mA or even 500mA fusing. |

| 776324 | 2009-06-11 17:58:00 | Still going fine with the 500mA fuse. | tut (12033) | ||

The first phrase is true only in reference to the basic fuses fitted close to the battery (or alternator) as part of the basic wiring system. Fuses fitted in the equipment, or it's connecting leads are normally supposed to protect the equipment. Giant fuses are used to indicate where the real fault is. (At the base of the plume of smoke.) ;) |
