No starter relay needed?

I’m installing a RIP kit gen 1 in my 2008 mutt. Looks like someone already installed some other unit that I can identify. It had a starter relay in it. I believe the RIP kit does not use one. Is that correct ? Please help me if you can. If anyone has a pic or chart of the flow from the battery I’d appreciate it. Doesn’t look like there is a circuit breaker either. I’m not sure A pic from the battery to ignition module would help me. Thanks guys. I’m obviously a beginner here.

Yes. This is the video I watched for install. I’d just love to see a 2098 mutt owners pic of the battery to breaker or fuse to see what the original set up looks like.

Generally speaking, makes little sense that it would not have a circuit breaker between the battery and vr for protection.

Same goes for the starter relay, if you have no protection from a low voltage circuit to a high, the switch will burn in a hurry.

I'm merely sharing food for thought. Circuit protection is paramount, especially on a Dog.

I can tell you, my 2004 and all the Dogs I've repaired have both along with all the HD's I've repaired.

Possibly, I'm not understanding the question.

Is the circuit protection included in the EHC? Is there a separate module? I'm not sure how the rip is designed.

How is circuit protection accomplished when installing rip?

These are questions for another member, I'd have to see and test.

Hopefully, someone else will jump in and provide more specific details.

seems the RIP1 doesnt use a starter relay it goes through the RIP ECH brain. Is that correct anyone? There is NO connection marked on the RIP kit for a starter relay. I.m new here so thank you all very much for your help!!

You definitely need a fuse or circuit breaker between the VR and battery. I'm not real familiar with the Rip kit. It may just have a output to the solenoid?
Hopefully someone else will chime in soon.

I’m sure about the breaker but I’m fairly certain that a separate starter relay is not used and is performed through the EHC controller.

No starter relay is needed. The starter button is a low voltage trigger to the controller then it will activate the higher current output to the solenoid.
Thanks for saving us Jwooky!

Just for my own knowledge going forward......what stops the back EMF created by the solenoid from traveling back to the ECM?

I ran into this problem on the good ole Shovel heads back in the day. Any coil or inductor causes this issue when the current is cut.

Is there an inline diode or is it built into the driver?

Thanks Boss

I will go from battery to circuit breaker, to the RIP EHC i suppose. I ordered a new one from Big Dog

The circuit breaker protects the Battery from a short or an over-current from the VR . The EHC connects to the battery and on a stock bike is not protected from a shorted battery. It is advised to put an additional CB or Fuse between the Battery and the EHC . Consider the possibility of the the Charging system working fine and the Battery shorts out. The original CB wont blow but your EHC will be toast.

I don't know the answer to that question but I have a 20 amp CB between the bat and ehc. with no issues. Contact where you purchased the RIP kit and ask for a recommendation.

You need to connect your VR to a separate 30amp breaker then to the battery. Your positive lead from the EHC should have a fuse of its own inline & connect directly to the positive post on the battery not to the breaker that the VR is connected to.

Any idea what amperage ?
