Car immobilizer defect and problem needed to be solved

Car immobilizer defect and problem needed to be solved

A high-quality cassette deck has been given which is by Grundig which I would like to use, but it needs a set of drive belts. I have not had good luck obtaining suitable belts here or overseas and wondered if any readers could suggest a source.

Also, we recently purchased a 1994 car which had an engine immobilizer fitted from new. The documentation for the car means the service manual indicates it was installed by Fortronic Forcefield Car Security Systems. All of their communication contact listings in the paperwork for them are no longer valid.

I am sure some readers here know anything about these systems and particularly, how to bypass or disable such immobilizers. 

It is operated in the way that a 6.35mm phono plug is inserted into a stereo headphone-type socket on the dashboard and then removed. We would have 60 seconds time or one minute time to insert the ignition key and start the car.

I see no brand on the immobilizer module. The phono plug measures 9kW tip to sleeve, 13kW ring to sleeve, and 22k W tip to ring. We have three plugs that all measure the same, but one does not work; that’s a separate puzzle. It would be very appreciative and be grateful if anybody had any information.

Finally, after 50 years or so of being an electronics hobbyist and building many loudspeakers, amplifiers, etc from different manufacturers, I am reaching a point where I cannot continue this at the same pace. 

I have the inevitable collection of bits and pieces leftover from projects that will not proceed as things are changing so rapidly in our modern world.

Rather than just dump all this stuff into the trash bin, I would like to see if any enthusiasts want all/ any of it at very reasonable prices. If anyone is interested, please feel free to e-mail me as I can send a full list back as an e-mail attachment for perusal. It is a mix of mostly new parts and a small number of slightly used parts.

I’m selling the items on an as-is “lucky dip” basis, and I am not offering returns/ refunds. I would prefer to strike an overall price or a price for groups of items, but do not want to sell them individually.

The list includes 8W l-pads, pan -el meters, 25 & 50W resistors, fuses, crossover PCBs, diodes, regulators, transistor mounting hardware, poly -switches, speaker connector strips, headphone sockets and plugs, RCA socket plates, plastic and aluminium knobs, Jiffy boxes, 100V line trans -formers, CB microphones (still in bub -ble wrap), heatsinks, RCA leads etc.
