Electronic/Potentiometer Help Needed
Hi guys
I bought a replacement potentiometer for my Kenwood R-5000 part # R19-9405-05 It's the the dual IF_Shift/NB dial. The problem is, on the old part, it only has 2 connectors on it for the 2 wires for each poteniometer. But on this new part, there is 3 connectors for wires. Which connectors do I use for the 2 wires? It's the right part since it was shipped from Japan and has numerous paper attachments showing it to be the right part. 2 wires but 3 connectors. BTW, sigh I am fixing a radio I bought from Radio-Mart when I first started out in SWL a while back. I know, I know... Lucky |

Provided that it is indeed the right part: There's left, middle and right. One of the wires on the old part is on either left or right (and the other is missing, as you say); connect it to the same side on the new part, i.e. if it was on the left terminal on the old part, put it on the left terminal on the new one. Then connect the other wire, which was on the center terminal, to the center terminal of the new part, AND to the unused terminal. Normally you'd leave the third terminal unconnected; this would give you the exact same thing you had. But connecting the unused terminal in this way tends to reduce the effects of dirt in the potentiometer, i.e. when it gets noisy it'll get less noisy. -- In Memoriam: Julius the cat April 1, 1993 - February 3, 2005 Never forgotten: Chane, Tigger, Koshka, Serenity, Rocky |

Left and right. No middle. Considering I bought this from Radio-Mart {oh it hurts to say this} it could be a part from a car. So you're saying connect the left wire from the old part to the far left of the new pot. Then take the right wire from the old part and connect it to the middle connector on the new part. Then jump the middle to the far right on the new part. Correct? Thanks for your help Lucky |

Left and right. No middle. That doesn't sound like a potentiometer. Hook an ohmmeter to the two terminals on the old part and make sure the resistance changes when the shaft is rotated. The "middle" terminal is the moving terminal, of course. -- In Memoriam: Julius the cat April 1, 1993 - February 3, 2005 Never forgotten: Chane, Tigger, Koshka, Serenity, Rocky Well, It's the same IF_shift / NB pot as the old one except for the number of terminals. Let me get my ohm meter out. Lucky |
