Bert2006 Posted September 21, 2014 #1 Posted September 21, 2014 Hi folks, My GPS (Garmin Nuvi 200w) has been loosing its power connection lately and I think I have isolated the problem to the in-line fuse holder. It is a glass type with a .75amp fast blow fuse in it. When I wiggle it power comes on and off. The fuse looks good but the holder is loose. I am looking to replace the holder with a waterproof blade type but the closest fuse size I can find is either .50amp or 1 amp. Will I hurt anything if I go with a 1amp fuse? Thanks
aharbi Posted September 21, 2014 #2 Posted September 21, 2014 You will be fine with a 1amp. Important thing is to have the circuit protected.
Bert2006 Posted September 21, 2014 Author #4 Posted September 21, 2014 Man you guy's are fast in responding. Thanks, will do the fix tomorrow morning.
frankd Posted September 21, 2014 #5 Posted September 21, 2014 It may be the fuse holder, but my Nuvi had another problem that caused it to loose power, and then come back on. It happened much more frequently on rough roads. I also initially though it was my fuse holder, but after tightening it up, I still had the problem. Then I noticed that my low battery electrolyte alarm (1st. Gen) wasn't coming on, and the same fuse fed the resistor that I used to permantly turn the alarm off. If my fuse holder had a problem, the alarm would come on also. I wondered if something wasn't jaring in the power supply itself, causing it to drop out. My GPS power supply is in the bottom of the right fairing, so I decided to wrap it in spongy packing, and that cured my problem. It's been 2 years now, and it hasn't dropped out once. If you still have a problem after you replace your fuse holder, consider cushioning the power supply.
XV1100SE Posted September 21, 2014 #6 Posted September 21, 2014 (edited) Thought the GPS called for a 2A fuse. ------- Manual calls for a 3A fast blow fuse for a Zumo 660 Edited September 21, 2014 by XV1100SE manual recommended fuse size
Bert2006 Posted September 21, 2014 Author #7 Posted September 21, 2014 Thought the GPS called for a 2A fuse. ------- Manual calls for a 3A fast blow fuse for a Zumo 660 Thought that also, but the hard wire kit for mc from Garmin has that hard to find .75a one.
Bert2006 Posted September 21, 2014 Author #8 Posted September 21, 2014 Changed the fuse and holder this morning and put a 1a fuse in. Also found that my battery terminal screws where stripped and loose, so that could have been the start of a larger problem. I replaced them with longer ones and now all seems to be snug and tight. Thanks again for all the help.

I was using a coil cord and the pressure on the connection on the rear of the GPS was causing an intermittent power loss. Replaced with a "straight" cord; no problem since!!!! Good luck!!!!

Somewhat similar experience. Took me a while to figure out that my problem was just at the plug into my gps.
