Loose cable in my Hacker GP42
Hi all
I spent today servicing my Hacker and have resolved the failure of the auto mechanism. It works great now! Whilst I was in there I noticed a cable coming from the bolt on the rear of the speaker which wasn’t connected anywhere. I can’t seem to find it on the schematic and wondered if anyone can help me identify it and tell me where it should go? Here’s a picture and thanks for any help! |

Re: Loose cable in my Hacker GP42
Hi.
It is an earth/Ground and the loose end fits on one of the chassis pins that you will see under the brown capacitor that is under the loose end in the picture, not sure if it is the first pin or second as I don't have a Hacker here at the moment, but you should be able to work it out looking at other wires connected to the other pins. Hope this helps. Gaz. |

Thanks Gaz. I’ve had a quick look couldn’t see it but I’ll take a closer look tomorrow.

Hi.
You can see a spare pin in the picture you posted. it is under the bend of the twisted white and yellow wire and the two other white wires. Gaz. Last edited by tracypaper; 13th Jun 2021 at 11:19 pm. Reason: Added more detail. |

Re: Loose cable in my Hacker GP42
Yep got it all fixed today, I managed to also repair the faulty on/off volume pot as well so my GP42 is working great now! It was a matter of removing the aluminium screening collar and giving it a good blast of Servisol. I also noticed that the collar was impeding the switch mechanism there is a little tab that sticks out of the side of the pot when the switch is operated, the collar seemed to be stopping it from working properly. Replaced it a tad looser and all is well!
