Looking through the manual I found these power supplies. ACC1 and ACC2 front and rear. Are these for powering accessories like a radar detector? Could you also run a trickle charger through these?

Stewart-

Yes. One is always hot (ACC 1) and the other (ACC 2) is only hot when ignition is on. Both are 10 A.

Trickle charger would go direct to the batttery.

I thought ACC1 was only 1A and ACC2 (switched) 10A?

 

[Guest]

I guess that use to be the case, but according to the 790 owners manual (pg. 201) both fuses are 10 A.

Yep, I run my TomTom GPS through the switched circuit. Photo attached. Decided not to bother fitting my radar detector and it sits unloved in the shed!

I would be really wary of wiring much to ACC1. The battery is not that big. Leave anything on by accident and it will drain to "will not start" levels pretty fast.

I'm designing a small circuit to use the ACC1 only when ACC2 is active. Basically a timer relay. Just trying to find a circuit that only goes live when the engine is running (not just ignition on). But it will stall draw 4mA - and that is not what I wanted. Thinking.

Thanks everyone, super imformative. I'm looking forward to getting my 790 soon and posting more. Great resource. Thanks again.

Mate - only just seen the photo - Those terminals look very open to failing or shorting. At least from the photo. Just a heads up.

You'll not have noticed then that the cable runs outside the headlight assembly. Just a test to ensure that everything works before properly completing the job. The photo is just indicative for where the connectors are.

I can vouch for this issue. When I installed the PP heated grips, I moved the USB adapter to ACC1. After a spate of bad weather, I went out to ride my 790 and found the battery dead – after only about 10 days! I decided to pull the USB off since I only used it when touring.

Interesting that the USB adapter draw so much when not in use - glad I went with my SAE connector solution.

A simple option would be to made a small Y-splitter harness and put the two devices on ACC2 - just need two very short lengths of cable and 6 spade connectors, two male (with two wires in each to connect to the bike's ACC2) and four female for your devices (USB and heated grips).

Well I had and was a bit concerned there too. But I try not to judge. I now have to find a way to get a timer relay in there - and it's not that easy. I may hide it under one of the lateral panels or the tank cover.

 

[EvansB2]

This was the excuse I was looking for to get rid of the USB adapter. I never liked the looks of it.

Thanks for the information. This will be very helpful.

By the way, I replaced the brand new stock battery for a 1.3 lbs 350 cranking amps Lithium. It's been awesome.

My Oxford Heated Grips ( half the price of the oem KTM grips and work perfectly) has a timer on them to shut them down when the battery drains a bit. Never have had that happen as I've remembered to turn them off so far. Its still a nice fail safe.

I've got heated gloves and was concerned about current draw too so I run them straight off the battery but the safety measure is a temperature controller clipped to my jacket which has an on-off switch.

This thread is really going sideways now.
I think heated grip is marginally useful. While your palm is hot, the other side of your hands is still freezing cold. Personally, there's no point riding when your hands are freezing.

You wait 'til you need to pee in near subzero weather. A chilly willy is no laughing matter when you can't even feel it!.

I've got a puzzle that I'd love some input on. I always hook up a radar detector to my bike and for the last 3 or 4 KTM's I've owned I hook them up to the ACC 1 or 2 up under headlight - add to that I use the HARD SYSTEM which sends a message up to an eye piece mounted in my helmet - I have to add I've had these systems for years and they've saved me literally hundreds if not thousands of dollars in tickets.

Now my issue - The HARD System is designed especially for Escort and I believe the Valentine detectors. When I hooked everything the detector works perfectly but when I hook up the "HARD System it doesn't send it to the eyepiece ( transmitter sits under the detector and receiver on the helmet) I have checked everything on other bikes and in my car and everything works perfectly except not on the Duke -= I sent the system with all components back to the manufacturer and he checked everything out at his end and all works great. What could be unique on the 790 ? No clue = anyone have a suggestion I/m all ears and thankful in advance - I/m about ready to direct connect it to the battery and see if that works but haven't had the chance to try that yet -

thanks
Steve
