Type 9 sender for an Acewell
i want to change from the usual magnet pickup for my acewell. Been looking at a 90 deg drive adapter as the gearbox doesn't have much clearance,
Europa spares one.
Then stick a granada sender in it which from what i can find has 3 wires.
The acewell only has 2 wires.
Will this work? and how would i wire it.
On the calibration part how is this done? i understand the magnet way of doing things but not with this way

Acewell wires are an in+ out- loop from the unit.
I think (but don't quote me!) one of the sensor wires goes to ground.
Hope someone can confirm as I want to do exactly the same

Is the granada sender from an MT75? If so this definitley works / if not maybe all ford senders are the same. The sender has a 12v feed (black), a
wire to earth (brown), and an pulsed 12v output (yellow). The output is too much for the Acewell which needs 5 or 6 volts. I ran the out put through
a LM7805 voltage regulator which reduced the voltage to the right level. Im told the voltage reg my not be up to high frequencies but it certainly
works up to 70 ish - Ill check how much higher it will go on my next trackday.
Youll need to work out the correct setting on your acewell for all this to translate to the right speed. Mine is set at 180mm per pulse.

So, instead of 12V+ can you not use the + output from the Acewell or is the sensor not up to the lower voltage?

The Granada sender (type 9) fits into the gear box from the side (and replaces) that the gearbox driven wheel is fitted from. You would then need to
seal the normal cable drive hole and tap the housing so that you could clamp the sensor into its fitment hole.
Yes it has 3 wires +ve feed, pulse and earth.
Hope this helps.

Well perhaps. I tried it and it didnt work but I dont really know why - and the voltage reg was only 90p so I didnt try it again

Not that simple I am afraid.
The acewell just switches to ground on the speedo input. One wire goes to reed switch, other side of switch to ground.

The supplied sensor is a reed switch but it will also work with a hall sensor - it just sees the pulse.

Hmm, the switch supplied with the Ace has two wires, both go back to the unit... its made of plastic and has no earth point.
My understanding is the Ace gives a voltage on the + and measures the pulse on the -.
Am I missing something?

A 7805 will work up to at least 5 MHz so you should be ok

now this is confusing, so it won't work the way i was hoping.
Any ideas on how to do this, i hate the magnet set-up

Right
A fused 12 v supply to the sender unit, from the sender unit one wire to earth, and one to the voltage reg ( or some other means of getting the
voltage from 12 to 6 volts).
If you use the LM7805, this has three terminals, Signal in (from the sender) earth and signal out ( to the acewell)
The acewll has two wires for the speedo pickup. One of these is a 5v out , ignore this and wire the output from the LM7805 to the other.
You can test all this of the car by spinning the sender inut end in a drill

just to check the LM7805 do i take it the signal wire from the sender connects to the input, ground to ground and the output to the acewell

Yes except connect the grounds to earth, not together.

i'll give that a go, any ideas on what year granada the sender comes from, going to try parts finder

Got mine off a FWD box, are they the same, and, where can I get a LM7805?

just a quick update, have made the small circuit and fitted all the parts except i get no reading on the acewell display. When the signal cable has a
multimeter on it the reading is 5v constant and changes lower when moving, but when connected to the connector on the acewell (0v one not the constant
5v one) it just earths and reads nothing. SHould i be connecting it to the constant 5v?

It might help to programme the acewell to accept a lower figure of pulses per mile to see if its registering anything at all ie set it to the largest
wheel circumfrerence possible and see if anything changes.

i tried it down at 50, 555, 1555 and nothing do you mean up at 5000 odd?
