Does the 561 need an inline fuse,and what size of fuse.

Jack,
Most microwaves have a fuse inside the unit. Make sure that you have unplugged the microwave and then remove the cover and look for where the power cord goes into your microwave. Follow the black wire from the power cord and it should take you to either an inline fuse holder or a small circuit board where the fuse will be mounted. You will need to replace it with the same size fuse and the amp rating will be stamped on one of the silver collars. Hope this helps!

Headlight switch has a built in circuit breaker (auto reset). Same with wiper.
ACCY (top fuse) is 14A.
HTR (left) is 14A
INST LT (center) is 2.5A
DOME (right) is 7.5A
CIG LTR (bottom is 14A)

Interior options (like radio and A/C) run off the stud on the back of the ignition switch and are separately fused (inline).

normally a 2 amp fuse is large enough but if you have had any modifications done to the radio for more power in any manner or had a veractor installed you may want to use a 5 -7 amp .

If a inline fuse in a holder the old one will aside from length have the amperage printed on it---very few mobile radios use larger than a 3 amp fuse-----look on metal ends of old fuse if have it for markings like 3ag 3 250---3AG is size, 3 is 3 amp, 250 is max working voltage (120 is fine).

Red- power Yellow-Memory Black-Ground

Unless the yellow wire has a fuse built into it then....
Yellow- Power Red-Acc/Ign Black- Ground

If the fuse you are asking about is on the radio t s usually a 10 or 15 amp fuse but if you mean for the power wire for a amp then it depends on the power amount of the amp....look on the amp and find the sum of the fuses on the amp and use a inline fuse that is the next fuse size sum...
Ex. 2 40 watt fuses on the amp then 40+40=80 watts so you would want to get a 100 watt fuse. Also remember you can never go to big for your inline fuse with a amp

Most un-modified CB radios run about 2 to 4 amps on transmit. A 5 amp fuse is sufficient for most radios. Check you owners manual for the correct size fuse to use.

Here's a wiring diagram

If you look at the illustration, it shows the center is an auxiliary power source. If there's nothing hooked on the tow vehicle's plug, you may need to run a wire to the switched side of the starter solenoid. Make sure you fuse it with an inline fuse. Make sure your wire in sufficient gauge and your fuse is ample to protect all your circuitry. you may even want to put a 20a circuit breaker inline and then run from cable that at least matches or is a gauge size higher than the trailer's aux power cabling size..

Could be many things, loose ground or power wire on the 561, there is an inline power fuse on the red wire leading to the control unit that may be blown. It may just need to have the remotes reprogrammed to the control unit, sometimes the control unit just stops recognizing the remotes. If you have recently had the cars battery replaced, or jump started the car, check the fuse at the control unit first.

hi steve

go online and type the following information:

inline fuse and anytype ofmarkings on the fuse maybe a size
enter

inline fuse 25microwatts
or
inline fuses for pci video cards

rod

If you were blowing an inline fuse, what size was the fuse and how big did you go up? It's possible the has a short in it.
