Well, I tested using the green wire into the coil and that ALSO interrupts on start!!!
1992 R80GS PD = switched live, without ignition interruption?

Something is not right with your method, If the bike starts and runs?
Number 1) what was still live when the LS relay was pulled out and left out ???
The Green coil live should definitely have been live with the the load relay out ??
I suspect something you are doing as your test method is actually the problem
Remove the green wire from the coil and fit a bulb in circuit (an Indicator bulb holder from one of the indicators with a couple of bits of wire is great for this!) between the green and any brown (Brown no tracers!) wire or communal ground or the battery negative and switch ignition on, the Bulb should light
and press the starter the light stays on now doesn't it
using an Indicator bulb is the next largest Load on the Airhead circuits after the headlamp and is a good inidcator of the ability to pass current without overloading the wiring
LEDs will light with the smallest voltage and absolutely minimal current
Whereas an incandescent bulb will actually show that the circuit can handle current and if the bulb is very dim try it on the battery directly or on another known good battery and see if you have change ?

You're absolutely right - my method was WRONG!
The green wire to the coil, when feeding the Acewell speedo, causes a reboot on starter button press.
HOWEVER, feeding a bulb from that green wire and ground direct to battery causes the bulb to DIM, but stay lit!
Volts drop to about 9v on that wire on my voltmeter.
It is my interpretation that the earlier suggestion of a substantial enough drop from the battery, that is not enough to turn off the bulb, but enough to cause the Acewell to reboot is the issue.
Implying that my otherwise fine seeming battery, may not be providing enough power to any circuit(!) for the Acewell to stay on when the start button is pressed.
BUT, if the interpretation above is correct, how is there enough power to crank the engine and start the bike without hesitation - every time!?
Am I misunderstanding the starter motor supply - is that by design, isolated from the other circuits and unaffected by the voltage drop?
It seems peculiar otherwise that I always have enough juice to crank the engine, but not enough to keep the Acewell powered on. The latter requiring a tiny amount of supply vs the former.

So to resolve this and cease any further confusion! I would personally just fit another relay !
fused (5 amp max) feed from battery +ve to Term 30 on Relay
Feed wire to Acewell onto the 87 Term
And just use the Green coil wire to term 85 and ground from term 86 to "trip the relay
30 mins and you are sorted and Let us know how that goes ???
That's a great suggestion - thank you!
So the Acewell will be fed directly from the battery when the new relay is tripped by the green coil wire - is that right?
Yup but remember to fuse the supply from the battery to relay
As a safeguard In case the wire chafes through upstream somewhere basically
If it's any help, I have an Acewell Speedo on my recently rebuilt Mikeyboy Special. Overall, I'm fairly disappointed with the speedo. (No reflection on Mikeyboy for this as we both agreed on the speedo)
It seems to be affected by something as the needle dances around the clock for no reason. I wouldn't get another one.
Mine too, reboots upon starting and so I have given up on resetting the time (and my bike takes some cranking).
Unless someone comes up with some answers, I just think they're a bit shit.

Surely the relay method above would work and you don't need a 30 amp relay you could use small form as per the 850s 1100s 1150s in their fuseboxes
You're probably right, but you're assuming my understanding of the word relay has moved on from my sports day at school from about 50 years ago.
I may pass on this information to a relevant 'grown up'.

If you can strip wire and crimp on spade terminals and Solder/shrink wrap joints ??
You can do this
My experience of Acewell has been overall very positive (get it?), but I had two issues with my first one, replaced under warranty.
First was the dial occasionally sticking, requiring a reboot (ignition off/on) to unstick. Second was the digital clock losing time. Yes a digital clock that didn't keep time.
Craig at Acewell UK tried to diagnose but was baffled. I eventually discovered myself that the clock was losing 2-3 seconds every time the Speedo rebooted, which as we know from this very thread, happens at least twice every time I start my GS. So the Acewell lost 5-6 seconds on each bike start.
Craig tested on a new unit and confirmed the behaviour which then was investigated by Acewell themselves and fixed via a firmware update (that the end user cannot perform). I have a video from Acewell acknowledging the problem.
Generally, with the oil temp sensor and remote handlebar control, multi-trip meter, voltmeter etc etc, it's a massive upgrade over the factory speedo and looks reasonable.
If your Acewell is resetting to 12:00 when it reboots on starting your bike, it isn't connected to permanent live correctly.
It needs a switch live for unit power and backlight and separate permanent power for the digital clock.
If yours is losing a few seconds every time you start, you have a firmware problem and should be able to get it replaced or updated by Acewell
Do you know if there's a way to keep it on the trip setting rather than going to rev counter on start up?
I quite like the sound of this handlebar control, but I'd guess it's more money than the current inconvenience.

I've had acewells on two GS paralevers and they have both worked perfectly without any problems so something is wrong somewhere. The ones I bought were plug and play units, very simple to install. No resetting issues etc. Only issue I had was them misting up on cold days. If it were me I'd carry on investigating to sort this problem properly
I have an OEM rev counter on my dual clock late paralever GS and don't use the Acewell rev counter - it's not wired in.
When you say "keep it on the trip setting" vs rev counter, what do you mean? Is your rev counter showing in the digital display?
My Acewell digital display defaults to whatever was last showing when the ignition was switched off - so any option, volts, either of the trip meters, temperature odometer, clock what-have-you.
It could be that if your permanent live is not connected, yours is actually factory resetting every time you turn the bike off and the rev counter display is perhaps the factory default?
CA85 user manual is here
I have wired as above but something is wrong.
Acewell does not get power with ignition on. That is term 87 does not get power (under 1v on my voltmeter) with ignition on nor ignition off
DVMs are poop, Just use the Bulb set up
Can you feel the relay Click when you turn on the ignition?
Is the ground okay ?? Stick the bulb between those two spades 85 and 86 and turn on ignition
12 volt perm live to term 30? Do you get a circuit With a bulb between that live wire and your ground ??
No click.
Bad relay? Looks new, was in a box of spare bits I have, but unknown origin .
