Hi guys and gals, as tittle says ive ran in to a little problem, as you probaly know ive been working on a nc 23 project and its going great that was till we changed the speedo for a digital dash, ive hooked everything up oil neutral etc, all seems fine till we turn on the lights( we used all original wiring and lights ) when ither lights turned on full, dip the dash seems to ither trip or resest it self. ive been working on this for a week now i seem to have drawn a blank, as i know a few of you have installed digital dashes i bow down and ask for your help :)
Im confident there is bound be a few you on here that can through me some ideas and i look foward to reading the posts.

cheers guys and gals

Without seeing how you've wired it it hard to say definitely the answer but it sounds like the headlamps are momentarily drawing a lot of power and causing the dash to crash/reset.

If I was sure that the dash was wired in correctly I would put a Capacitor across the +ve and gnd supply lines. This would charge up when the dash was powered up and would hold the voltage up if there was a momentary drop in the supply voltage due to headlights drawing power.

something like this bad boy (35v rated 1000uf)

Maplin will stock similar but just cost a bit more (quid or two). It just has to be rated over 12v...but most are 16 or 35v which is fine.

Disclaimer: This is what I would do if I encountered the problem you describe, but it may not be the correct solution for you. If you are unsure about anything above please check with an qualified electronics engineer.

It's a good idea, but I would say that if it's right then it points to a bigger problem, ie. dead battery.

Thanks for the replys after reading may be the battery, i went and charged it till was fully charged, after that reconnected it and started up the bike and success the lights worked without a problem :). i guess i need to have more confidence in my electrical skills(doesnt help when u got ya dad looking over ya shoulder shaking his head saying its the wiring or your doing it wrong lol) thanks again for all those who replied
