12v plug for gps



A CAUTION to some that are tapping into the DC side of the ECU/Chassis harness.

I've been looking into the electrical system on our DC-CFI-2 RMK's and have some decent insight into the system the I hope others will find helpful.

Actually the amp mate n lock connectors are ONLY for the Power INPUT for the ECU and DigitalWrench console.

The connector labled "DC PWR" is a Power input for the diagnostics.
That connection is un-fused and could wreak havoc with the ECU function or durability.

Best to tap into the FUSED connection in the hood harness and do not run anything off of it that will draw more than it is fused for at 2 amps...REGARDLESS of what others may be saying.

The red/white wire powers draws from the same red wire, through the chassis relay, that powers up all the vital functions on the sled like ECU, Fuel Pump, sensors, MFD etc.

If something goes wrong or shorts there... then you could have an expensive problem on your hands... easy to do since that is not fused.

IMO... DO NOT use the "DC PWR" connector for to power up ANY device... Any aftermarket items that run off of this connection are putting your sled at risk and should be changed to the fused circuit. In some cases, the aftermarket mfgs of dc powered items may be making assumptions that could put your sled at risk.

does any one have pics of how they mounted their gps to the sled

Sorry, don't have a pic, but I would like to share my thoughts when I chose right mount and right place for GPS unit.
First - use OEM holders for given GPS unit. They fit the best, and hold the best - just find proper (strongest) one for your application
Second - choose mounting place, where GPS unit is not going to be affected by roll-over. This is true for trail only sleds too.
Third - do not use Velcro, 2-sided mounting tape, etc. Only screws or bolts
Fourth - do not connect GPS unit directly to battery on ES units. If you forget GPS unit on sled once, you might have dead battery.
 
As a note... Regardless of what ANY aftermarket mfg says, NEVER, EVER, install a fuse larger than factory installed 2amp for the "DC ACC" connector by the headlights... and also, never run a motor load of any amperage off of this connector.

This is a LOW AMP connector that draws power directly from the ECU power supply... by drawing more power than intended you could damage the ECU and/or the voltage regulator OR affect how your sled runs. If your device blows the 2 amp fuse... It means that the fuse is protecting the factory ECU/VR correctly.

DO NOT connect ANY loads to the connector marked "DC PWR" located on top of the Clutch Cover wiring-bundle. This draws power from the same location as the "DC ACC" plug BUT it is not fuse protected. The "DC PWR" connector is a power INPUT for ECU diagnostics even though it has power when the sled is running.

There are turbo and aftermarket parts companies are drawing power from this connector INCORRECTLY.

The Tyco Connector, shown in the post above, mates to the "AC PWR" connector located in the bundle near the clutch guard.

Also to note... if you want "clean" power... the capacitor is a must.

If you value your sled, and the reliability of it, you should also protect each load with its own fuse.

Nice fuse blocks (look around the site... they have lots of good wiring stuff... vinyl tube to protect wires, connectors etc)

These are also a nice clean fuse block on Ebay

So after reading this thread, I installed a 12v socket in the dash on both of my 12 Pro RMK's. Excatly same parts, and procedure. One has power, the other does not. I have swapped the sockets, connecter wire, and GPS 12v chargers on each sled and have come to the conclusion that I don't have power in the accessory plug in on the hood. First logical thought was the fuse, which I will check tomorrow, but I've never had anything plugged into the accessory wire before, so a blown fuse seems strange? Any ideas?? Will report tomorrow on what I find, and post pics of my setups.
 
OK, the plot thickens. On the 163, (the one that did not have power after original setup) I checked fuse. It's blown. Ok, put in new fuse, fire up sled, no power. Check fuse again - blown.

Plug GPS into the 155 (the one that did indeed work with this GPS when I originally set it up). No power. check fuse in that sled. It's good. What the front door is going on. Shut of sled, fire up again. No power. Check fuse. Blown.

The GPS i'm plugging in is a Garmin Rino 655t. The spec on the cigarette charger for it is: input and output 1.4amps, fuse spec 2 amps.

Anybody? Mountainhorse?
