Then you might get a fairly good ground right there. Bolt the bracket right to the aluminum and run the black power lead to one of the bracket bolts, cutting the wire as short as possible (no longer than six inches should be fine). After working with it today I feel the alternator is the primary problem. Since I have no ignition and no whine with the key in the ON position (Fuel Pump), the alternator seems to be the culprit. I have been reading about installing a micro_farad capacitor between the alternator and ground in order to steady the voltage thus reducing the whine. I understand the theory but could use some feedback about the practical application. I feel this might be my least time consuming and least expensive solution. You could try that, too. Find yourself a 'motor run' (NOT a 'motor start') capacitor of around 1 to 5 uF. They usually have tabs for terminals so you can use crimp connectors, and they can be mounted just about anywhere with a cable clamp. Mount it as close as possible to the alternator, or even right on the alternator if possible. Run one wire to the output and the other to ground, again keeping the wires as short as possible. The capacitor is not polarized so it doesn't matter which terminal goes to ground. But know that some regulators are messed up by putting a cap across the alternator. If you screw up your engine, don't blame me. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- Well I have learned a tremendous amount about whine in a CB Not from Geo, but that's OK. He's useless, except for tax purposes. |

Yes , I have already noticed alot of background noise where there was none before. I have already saved all of these post. When I have more time I will apply what I have learned. You will probably hear from me again ![]() |

What started it? N8wwm getting his clock cleaned after harassing cbers
for discussing various aspects of radio. His butties KC8LDO, N7VCF, WA3MOJ and N3CVJ all ran to defend him and his (felonious) law breaking ways while harassing others. They pushed too hard and sealed their own reputations as law breaking lids and have been angry ever since. They blame everyone else for their self-created misery and take no responsibility for their own actions. Hence their tired acts of trying to get off-topic personal information on those they are unable to debate intelligently. When the tables are turned, they begin to menstruate all over this group. They have always been able to dish it out but must be forced to swallow their own bitter prescription of what entertains their double-digit feebled minds. |

Hello Frank
Can you recommend a book or two that will teach me about CB fundamentals, repairing and tweaking? I have an little electronic background and even own an oscilloscope. I think that if I learn the workings of a CB from the ground up it will be easier for me to troubleshoot them. The first book should be very basic so I can get the fundamentals down before diving off into the deep end. Thanks "Frank Gilliland" wrote in message ...
