power valve activation

[mbmO8]

hello all I recently installed an LED tail tidy and a brighter main bulb onto my 99' dtr the isue I am having is that when using the high beam my power valve doesn't seem to open. I have a feeling that it is due to the load on the battery with the new parts but I am no to sure any help would be very welcome, thank you.

addons I have :

. 12v 100/80w main bulb

. Oxford hot grips ( although they where not turned on when I experienced the problem)

.LED tail tidy and LED rear indicator with resistors in place

If the cabling is not messed up the main light runs directly from the stator, doesn't load the battery.
