I cannot seem to find where i could buy one from ..

If you have or could make an account at http://www.ebay.com/, you can get 10 for US $1.70 from http://www.ebay.com/itm/10pc-SMD-Voltage-Regulator-IC-78D05-5V-0-5A-TO-252-UTC-/131872655850?hash=item1eb43909ea:m:mewwUp7l5Q3g0cQ2z133Efw.

thankyou jim i afraid it shows nothing at all no voltage

No voltage at output pin? What about input pin?

Here's its datasheet.

Looks to me like an industry standard part. TI or ONSEMI or anybody's 7805 should work,
usually i suggest getting the same package, dimensions are industry standard too,
but for your repair one of the TO251 's would work if you can bend the leads to make it physically fit so you can solder it in.

You could get one at Radio Shack just to try out. You might find one in a discarded VCR or wireless router, they're a very common IC.

good luck

Just an update after week of trying I have given up I replaced most parts and managed to get 11.3 volts on the output pins the battery was 11.1v so I thought I was on to a winner but alas no nothing worked I connected my desktop power supply to the knob on the handle bars and managed to get it to light up with 15v I'm not sure what's up but I have put back together before I forgot how it all went still had fun with some soldering and trying to work out how it all worked I failed but it was worth it
Anyway just wanted to thank everyone who commented and tried to help me
