  1. Right guys, I pretty much do this anyway but thought Id post up make it more organised and see if anyone else was interested in this. Had a word with Les and he is OK for me to post this up..... so..... Basically I'm willing to lend a hand to members of the forum with regards to maintenance and mechanical issues. Those that wish to do a similar thing in other areas of the country may also post up their info in here. The more the merrier, but please only do so if you are truly comfortable working on someone else's car. Please Remember!!. . . . . . It is expected that you are able to travel to the location of the member offering help, not them travelling to you! Members offering assistance may not be mechanically trained and can not be held responsible for breakages/damage caused during jobs. Although care is taken to do the best job possible. If the job you need doing is too complex or critical, the person(s) offering help in the area have the right to decline help and as such advise you to use a Dealer or Independent garage. This is also the case if on initial inspection the work required is not as discussed. Where again, you will be advised to visit a Dealer or Independent garage. There are no warranties and no guarantees on any work done. Visits should be discussed and arranged in advance. Any parts and consumables should be supplied by yourself and in good working order. This is an offer of help to forum members, it is not here to be abused. This offer of assistance is in no way related to, or associated with the TOC forum and its staff. Always use a dealer/independent garage if you have any concerns

  2. OK.......the head unit ( Radio ,Audio unit )...whatever its called. Is mine a " Double Din size "....or " 1 1/2 " Din size please. Only reason i'm asking is that i'm considering a Nokia Lumia phone upgrade shortly,and may need a new Audio unit ( aftermarket ) one. The new unit must have blue teeth...lol.....oops sorry.....blue tooth !. So i can play music wirelessly through it from the new Lumia phone,as i Hate having wires / cables dangling everwhere. Considering spending the extra and getting a full touch screen multimedia player.

  3. With regard to a DC motor, the voltage across the motor, minus IR losses, is proportional to the speed or RPMs of the motor. The current through the motor is proportional to the torque produced by the motor. Normally the back EMF created by the speed of the motor opposes the voltage being applied and limits the amount of current the motor draws and thus it's torque. As more and more load is applied to the motor, the motor slows reducing its back EMF allowing more current to flow, producing more torque. With a lower applied voltage to the motor not only will the motor be turning slower, which reduces the back EMF and allows more current to flow, the losses such as the internal battery resistance, the cable loss and the IR drop in the motor become more important. This may mean that the motor may not have the speed or torque to turn over the engine and stall. When the motor stalls there is no longer any back EMF and all the current goes towards heating up the motor windings and that can damage the motor. Pete.

  4. HI guys, I dont use the site a huge amount but im a mechanical and electrical maintenance engineer by trade and my hobby just happens to be rebulding engines and cars so if anyone in east anglia (particularly, im afraid to say, good ole backward Norfolk) needs some free advice or assistance gimme a shout and Ill gladly help where I can. I will not do painting for anyone though as I havent the time or patience lol!
