Here you go George

TTT for George's PM.

Gotta love the Mouser relays in stock for $1.42 each

Mouser HAS 570 of the 871-1A-S-R1-12VDC in stock for $1.42 each

yep just ordered 5 for like 15$ with shipping thanks for the heads up MH. I have ben keeping an eye out for something that was in stock that would work but know next to nothing about electoral components so I appreciate you looking for a suitable replacement for us! thanks again MH for your time and knowledge!!!

 

[mountainhorse]

Looks like they've sold 30 in 3 days.

I've been getting a LOT of PM's and emails on this lately... and where to get the relays at a reasonable cost.

I strongly believe that you can use the 871-1A-S-R1-12VDC. (instead of the factory 871-1C-S-R1-12VDC)

The 1A and 1C exact same relay EXCEPT that there is no second pole... which is NOT used on the AXYS Mtn sleds ANYWAY according to the wiring diagram.
See this tech page if you need confirmation of this information.
https://www.mouser.com/ds/2/378/20098291912159610-3428.pdf

If the relay has only 4 wires going input terminals (even if there are some terminals with two wires each)... then you can use this relay as it will be electrically identical to the 1C model.

WAYTEK has the 871-1A-S-R1-12VDC in stock for $2.55 each

If you must have the 871-1C-S-R1-12VDC.... you can get them direct from China through AliExpress (they are made in China anyway)...For $2.01 each with $2 Shipping in 12-20 days.
HECK.... If you wanted to buy 100 of them... you could get them shipped to your door via FedEx in 5 days for $2.38 each.

has anyone used these and can actually confirm these work?
(not that I am doubting)

I had to do trouble shooting and swapped out all 3 stock relays with the Mouser and have had no issues.

those new ones without the center pole MH posted?

I have the Mouser ones that are identical to the factory, but want to get a few more sets.

thanks

 

[Ski-Dont89]

i ordered 10 from the aliexpress link that MH posted above on 1-27. Hopefully they get here before feb 14

 

[mountainhorse]

You can see in the factory wiring diagram, the center pole, Terminal #4 on the connector is not connected to anything.... so it is a dead terminal on the relay.
Not needed.

Just looked into it.

If you replace one... replace all three with sealed relays.

Make sure that the relay you use also has a resistor across the coil (trigger) contacts... like the stocker (they come 3 types, resistor, diode or nothing across these contacts)

I believe that the factory relay is 15 amp... you could go up to 20, 25 or 25 amp in the same housing I believe ... and get a sealed unit.

There ARE sealed Micro-ISO relays (compared to non sealed).
Littelfuse part number would be MA-250012-RS [MA250012RS] (SEALEDSPST with Resistor).... OR... MC-250012-RS [MC250012RS](SEALED SPDT with resistor)... you can use an SPST or SPDT because, it seems, that Polaris uses a SPDT relay but configures it only as a SPST (unused terminal 87a)

whats the difference between the cm1 and the cm1a? reason i ask is mouser just sent me the cm1 version. 10 of them...

 

[Benson_chris]

Had this issue today and all three relays are the “sealed” ones. Not sure what that means tho because there is no rubber seal preventing water into the contact. I have no dash and the sled has no power and bogs and dies. Which relay(s) affect this??

With how inexpensive they are just replace all 3.

Stock ones are not sealed

Mine are...states that right on the relay and I'm still running the original relays on my 16 Pro-RMK.

The problem isn't the relay, it's the junk connector coming off the harness allowing water to run down corroding the connections.

The CM1 is a SPDT, just like stock relay. The CM1A is a SPST, it doesn't have the extra "blade" which isn't used anyway. Both relays will work.

heres stock junk not sealed and new solid sealed ones

fixed many dead sleds this yr because relays no good

 

[mountainhorse]

Caltrex...

These are sincere questions.


How is the one on the right different from the one on left?

I only see the factory relay on the left peeled open.

Have you done the same to one on the left?

What about the factory relay was not sealed?

Those are 5 new solid ones in 2nd pic.

You can't open the solid ones

You can see how cheap the stock ones are

What trouble shooting did you have? I found the single relay by the clutch in the bag was corroded but when I swap it for one of the good relays up top it doesn’t fix my issues. Are you saying you had to switch all 3 in order to fix your problem?

Thanks !

Hope you can bear with me for some more questions...

I don't see any internal corrosion on the one on the left (OE).
It may be able to be opened... but I do believe they are sealed from the ones that I've taken apart.

What relays are you using... The Panasonic's I have listed?
What is the Resistance value across the coil on yours? (or does it have a diode??)
What part-number/brand are you using? (got a pic of that end of the case?)
