triumph trw electrical installation
« on: November 14, 2022, 12:17:58 AM »
Hello everyone. I have many problems with the electrical installation of my TRW. When I turn on the headlights, the ignition suffers and the engine fails. The bike is old and poorly treated, I don't have the headlight resistors or the large switch key that goes to the right of the headlight. Has anyone installed a modern rectifier-regulator on these bikes? My intention is to put all the lights on direct current from the battery. Originally, the ignition coil works with direct current, and the headlight with alternating current. But in this situation the light of the headlamp only comes on with the engine very revolutionized. and when I turn on the light, the engine misfires. I intend to put the lights with C Continuous, but since the original bike does not have a regulator (only plate rectifier), I am afraid of overloading the battery and bursting it. I think I should also put a regulator.
Thanks for the help

Hola a todos. tengo muchos problemas con la instalacion electrica de mi TRW. Cuando doy las luces del faro el encendido se resiente y el motor falla. La moto es vieja y mal tratada, no tengo las resistencias del faro ni la llave de conmutacion grande que va a la derecha del faro. żAlguien ha instalado un regulador-rectificador moderno en estas motos? Mi intencion es poner todas las luces a corriente continua procedente de la bateria. En origen la bobina de encendido funciona con corriente continua, y el faro con alterna. Pero en esta situacion la luz del faro solo enciende  con el motor muy revolucionado. y cuando enciendo la luz, el motor falla. Pretendo poner las luces con C Continua, pero como la moto de origen no lleva regulador ( solo rectificador de placas), tengo miedo de sobrecargar la bateria y reventarla. creo que debo poner tambien un regulador.
gracias por la ayuda

If it has an alternator with permag rotor,the output cant be regulated,only shorted to earth by a Zener diode at 13v.+..........you cant use AC in an ignition system ,so its probably best if you rewire the alternator for full wave rectification using modern diodes.,and ditch the old metal oxide rectifier.......if you need a power  drain ,have the headlight on all the time.
