We probably (I know, I have to check the serial number, but the tractor is two hours drive away) have a TEA-20 that was restored about 18 years ago. It is in fairly good condition, with the exception that it will not start when it is warm. After having maintained the carburettor and changed the start switch, I suspect an electrical problem. What puzzles me is that every drawing I have seen, and all the forums, tell that it should be a positive ground system. Our tractor is not. The negative terminal of the battery is connected to ground at the back side of the steering weel. Also the negative output from the coil is connected to the distributor. Otherwise the wires are connected the usual way.
Before I change it to a positive ground 12 volt system, I believe I need to be sure if I have an generator/alternator. But how do I tell if it is a generator or an alternator? It has two wires and was manufactured by Lucas.
Final question: What is the purpose of this device?
Any help is very much appreciated!
