Trandsponder question

generalee69 · 05-23-2009, 09:00 PM

I figure motorsports was a better place than electrical.

I'm hard wiring in my transponder. I am planning on using an "add-a-circuit", but not quite sure what amp rating of a fuse to use. 5A? 2.5A?

I don't think it draws to much, but I don't know s@#% from shinola when it comes to electronics.

i doubt a transponder draws much current, but it might be listed somewhere on the device. most electronic devices have the amount of power or current they draw. generally, 1.5-2X the listed power would be plenty of power without tripping the fuse while still giving you some protection from a short.

The response I got from one of the race forums I visit said they thought that it drew 60 milliamps. So like a .5A fuse. The smallest I found was a 2A.

I don't think I am going to worry about it frying. I just don't have the install instructions because I bought it second hand. I wanted to get some other input before I just stuck in the 2A.

Thanks.

yeah, i'd just put in the smallest fuse you can find (assuming it is at least .1A) to make sure it doesn't get a huge surge.
