I have a nikon sb700, battery leak. I clean and sand away the rust at the contact metal at the door. I also tested with a muiltmeter. Inside does not corros. It’s still not working. Nikon service center does not repair. Any advice. Thank you
Years ago I had the same with the Nikon SB-26, alkaline batteries leaked and corroded things. Never worked the same again when using alkalines.
At some stage I tried it again with Sanyo Eneloops and it came good. My theory being that the Ni-MH batteries are a whisker longer than the alkalines and make firmer contact with the corroded but cleaned contacts. Now it is reliable even years later,
Later changed over to IKEA LADDA batteries as they are same as Eneloops but way cheaper.
