Blowing blower fuse

[NHarp1]

I have 76 hours on my 2012 RZR and now have blown 2 fuses that control the Tige touch Medallion system. Blower works for 6-7 starts and blows using a 7 and 10 amp fuse. Blower works by removing the carpet access pannel that exposes the main breaker pannel where there are manual switches that can bypass the Medallian system. Blower works fine with manual switch. Blower yellow wire is tight going to the Medallion system, not touching anything. No obvious loose wires anywhere. Could the blower motor be causing the fuse to blow? Everything else works fine with Tige touch. Any suggestions?

I am at Norris Lake TN this week.

I have had the same issue.

What size circuit protection is used for the manual switch as compared to the fuse on the Medallion side? I see no reason for them to be different as the load, i.e. the blower, is the same.

Pretty sure there is a recall for this?? Might want to contact you dealer.

U need to get a diode installed on bilge and blower. This appears to have fixed issue on my boat. Dealer should have them.

[barry1me]

dealer already did the diode recall and Im still having this issue.

Diodes have polarity, so maybe its backwards. Hard to say without seeing the service bulletin schematic.

Same issue with mine - Harvey is sending me a diode, but same story. Put a 10 amp in the medallion and then it pops the second in line fuse. I put a 15 amp in the in line fuse and still popping 10 amps in the medallion. Hopefully the diode does the trick - will let you know.

If the diode comes with a schematic and explanation, id love to see it. I think I get what they are after.

What are they after? A diode prevents feedback right? Is there a fundamental error in the wiring that the diode is a band aide for?

The blower was getting back feed and would continue to run even when shut off causeing to get hot and blow the fuse the diode is a switch stopping the back feed, havent had any issues with the fix.

I believe it has something to do with induction in the motor(Maybe same as back feed). When the motor is shutoff the coils of copper in the motor produce some huge reverse voltage. The diode prevents this from getting to the Power Module. The Diodes I received contained no schematic but I have seen them hooked up in 2 ways on the power panel.
Option 1: on Ballast Pumps wires ,appear to be in Parallel with the wire going to pump.
Option 2: On Blower and Bilge they appear to be inline with the wire.


From research on the net sounds like anytime you are dealing with a coil of wire you are at risk of this. Some motors and relays actually have the diode built in.
I think its called a Flyback Diode.

barry, you may wanna double check the placement of the diode if you have not already. I made that mistake on mine when installing the first time. It only goes on one way but I grab the wrong wire.

What's interesting is that there are diodes on the ballast drain pump wires but not on the fill pump wires.

[trent]

I will have to check later but I thought I had them on all the pumps.

Thats because you can manually drain the ballast if the TT fails. Each drain pump can be activated by 2 means.
