Landing Light Weak

I have noticed my landing light seems weak so I decided to change it to a halogen 4509Q. Replaced it and the 4509Q does not come on. Put the old one back in 4509 and it does come on but is weak like before. I replace the connectors on the end thinking bad connection, but nothing changed. I checked the new bulb with an Ohm meter and it seems good. The wiring looks original with the braided shielding as the ground. Anything I should check other than wiring?
