How do you change the fuse in a 6600M?
Kind regards and 73,Don

Could it be the power supply rather than the radio? That would be my guess.

Taken from the manual downloadable 6600 hardware on the website
The power input has a protective 30 Amp automotive “blade type” fuse inside the radio case. In the event you ever need to replace the internal fuse, remove the top cover and locate the fuse in the rear corner of the PA board just inside the case adjacent to the Anderson Powerpole connector.

I would contact Flex and ask.. If it was the fuse, something must have gone wrong. Simply replacing it may not be a good idea.0

Power supply is still working. It also runs relays that are active. I read that part of the manual...there are two boards above the Anderson Powerpole connector. Wouldn't it have been simpler to put a fuse on the hot wire coming into the radio...:)
Thanks for your comments. Think I will try your approach Bill.Kind regards and 73,Don-WY6T0 -
Don, they are having phone trouble now

I really don't care for this design starting with the Anderson Powerpole connector and the power cord is short and no inline fuse. Looking at the wonderful power cord that is supplied with my Icom 7600 it is very cheap to say the least. My powerpole connecter on my 6400M is bad it won't lock the cord in. Flex makes a wonderful radio don't get me wrong but I feel the entire design with there connectors need redesigned. The screwy mic connector and on the rear is a poor design.......... SO let the flames begin .

Are You sure the fuse is **** - Take an ohmmeter to check it if you can
I had a problem with the PowerPole itself, if the Blades are not sitting correctly, a voltage
drop occurs and causes a higher resistance - had to change out Power Poles to make
sure their connection is good on Cable - but can happen on Radio side also

Yes, the mike connector seems like it could be a problem one day, but I made an umbilical for headphones, mic, and key. It works fine. For non Flex reasons I made another power cable with suppression. Power poles always leave me a bit flummoxed and I used two tries to get them right; it’s the blades. The the PP’s lock up nicely. That said, my short #10 cable works good, almost no voltage drop as measured inside of the radio. I should have a min/max standing order with parts express and mouser.1

Agree......it’s the blades..... the 40Amp Blades are better than the lower
Amperage Blades ( Cause Issues ) on Power Poles

I had my power cord come unplugged ... I hate anderson power poles such a pita Maybe your cord came unplugged like mine.0

Tim - W4TME, Customer Experience Manage
- The reason we did this is that since the shift to using the Anderson PowerPole power connector, the feedback we received was that customers did not primarily direct connect the power supply to the radio. The use fused power distribution block to power other peripherals and adding in-line fuses would result in redundancy and creates additional resistance that lowers the supply voltage to the radio causing it not to put out full RF power.

And to further explain why inline fuses are not a good idea,or not needed
- I don't agree that fusing negative wires on ham shack equipment is generally a good idea.
A non-vehicular ham shack (assuming you don't live in a metal house which you are using as your antenna ground plane) is a different situation. There may be other shack DC-powered devices that don't have fuses in their thinner DC return wires, such as external antenna tuners or powered antenna switches. If that Flex radio ground fuse opened up but not the positive fuse, the next time you transmit you could end up with high DC current taking paths such as antenna braid to these other devices with the thinner DC wires to your power supply return. Fuses introduce low but non-zero resistance, and sometimes open up unexpectedly due to poor connections or internal failure. I suggest giving careful consideration to how your specific shack equipment is powered and grounded. There is a reason why even fused AC appliances do not have fuses in their safety-ground or neutral (in the US and similar) wire, and I believe this is a comparable situation.
I'm not saying it is never a good idea to fuse both positive and negative in non-vehicular setups, but often there may be unexpected consequences. Also, if your power distribution is already fused at reasonable per-circuit values, adding additional fuses in positive power wires doesn't buy further safety but does introduce more voltage drop and possible points of failure.

These replies here should show that there is a lot of dislike in this choice. And to ''just pull off the cover'' to change a fuse means removing several screws which is not a well thought out design. Let's be honest it was a cheap and dirty way along with engineering not bringing the mic connector and headset connector to the front of the radio. Can we once "all you fan boys of Flex " accept the truth. I only am being critical here in hopes that the powers to be will see I still love my Flex and won't have anything but a Flex. However there is always room for improvement.

No problem Doug your opinions are welcome.0

I don't think there is a chorus of dislike fervent for all the years of Flex-6000 series production.
If a user wants to change their unit's fusing arrangement to depend on an in-line fuse in their power cord, the modifications are trivial.
If you search the discussions on connector locations you will find lots of discussion, both pro and con, concerning the present and what was then proposed connector locations, types and sizes. There may have even bee informal surveys done at some points.
Connectors and things like fuses were all well discussed within the community, so nothing cheap and dirty, nor unexpected.
I share with you a preference for power connectors that are physically more secure than PowerPoles, and prefer font-face access for usual connectors. But then on my 6700's I found myself using the rear panel balanced connector in the end despite front panel connectors.
Reserving front panel space for connectors was a community discussion, with FRS making the economic decision to put them where they are.
Again a fix is using short patch cables.

So this thread has a lot of noise in it now, getting back to the topic Don did you ever get this fixed and was it the fuse you suspected to be the problem or was there another issue in addition or instead of the fuse which was the cause of your operation to be terminated early?1
-
I have had the same experience but it was the fuse in the power cable that went. I wish they opted for the automobile type fuses instead of these buss fuses in the power cable.0

Mark
The cables that are sent with the radios do not have fuses in the cable. The fuse is actually in the radio and it is a 30A fuse.
Are you sure you are using the correct cable?
You can see a picture of the cable here. http://cart.flexradio.com/Power-Cable-for-FLEX-6000_p_979.html
