My battery of my speed four was dead this morning> I got it started with the aid of jump leads from a handheld battery. the engine malfunction light has remained on even though the bike`seems fine. i have the battery on a trickle charge now. what do i need to do ref the light still on ?

The engine light is not a worry. When you change a battery on a speed four the management system resets. What you need to do is let the engine go through a cycle of reaching working temperature and cooling again. This allows the management system to relearn the working parameters. Once this is done the engine light will go out.

I think your alternator needs repair/replacing. Of course it could be several other things, for example, your charging rectifier may have burned out. If you can find it, you can test it with a contunity checker. Power should pass in only one direction. If it passes in both directions, it can charge (sort-a) but it will also drain the battery. And, it might be time to replace your battery.

My concern is your 'check engine' light. I would expect this light is tellng you the alternator is not putting out.

I suggest you have your Triumph looked at by a professional. You certainly don't want to be pushing that thing home some dark and rainy nigh with your date on the back!
