I said aMal so perverts need read no further


Anyhoo I cant find my manuals disk so I thought Id ask on here, my Sapph stopped boosting as much as normal the other day and I have just had a quick check of it. The Amal is activating with the ignition on but then once running it does not. No clicking if I unplug and plug back in, I checked with the power probe and it has no earth while the engine is running, as soon as I earth it with the probe it clicks back to life again. Is the Amal earthed straight to the body or does it run with something else? I was planning to just run an earth to it myself is it safe enough without bollocksing something else up?

Cheers in advance chaps and chapasses

Oh well best not read any further lol

I already know you like anal big fella

The AMAL valve is a negative trigger mate so it will be a case of tracing the wiring back to the ECU and trying to find a break/damaged section. If you just earth it, it won't pulse, it'll just hold open.

BigErn

Cheers Will, Ill have a quick look at it now, while its still sunny

Captain500rs

Have ya tried cleaning the terminals mate,mine was doing this not so long back would only boost to 1.5 bar pulled the plugs off, cleaned them and was back to normal,

BigErn

Karl, Im gonna look at them now and do a bit wiring checking

If it was held open would that cause any issues?? Would it over boost??

Scrap it

BigErn

Perfect continuity between pin 16 on the ECU plug and the AMAL itself. Seems to be a problem within the ECU maybe? Will? Stu? Anyone??

pa_sjo

What load conditions did you check the Amal valve? If at idle/not moving then it won't be doing jack..

BigErn

I was always of the understanding it should click when you plug it back in while car is running? Sure others of mine have done it in the past?

How do I check it properly then? Maybe that would help

Ian if you want I can drive while you hang on for dear life under the bonnet

BigErn

Sounds like fun, but you drive like a girl so it would never get full boost anyway

big cunt'll get a clip...................................: cry:

Working purely from memory here, just check for continuity on Pin 16 with the idle valve as well mate, from memory, the 12v feed is the same to the AMAL valve and the idle valve and then they have negative triggers.

If you do find you have continuity, switch your meter across to VDC and check to see if it is indeed positive voltage.

If that is the case, then Pin 16 isn't the AMAL valve negative trigger

Ryan

yeah ISCV and Amal share the same live (fuel pump live) you will only see 12v at both during pump prime and when engine is running.

p16 is amal, p34 is ISCV, both switched earths.

foreigneRS

both PWM

Ryan

yes

Have you got it sorted ian yet. I got excited to cause i thought it paid anal too lol.

Captain500rs

Na thats just what you pay for lol

BigErn

Peter, if you dont be patient Im gonna fuckin tea bag you

Glenn, if you want to pay for anal then drop Pete a PM.

Will and Ryan, cheers Ill have another look during the week, or maybe next weekend. Gonna slob about the house now with a few cold ones

BigErn

Something I have just remembered is coming back from Scotch Corner last week the car started "idling" at 4500rpm so I unplugged the valve presuming it was sticking open or fucked, it was still boosting fine while revving high when you gave it some foot. Drove with it unplugged and never really used the boost till later on and noticed it was low. Sounds like theres a connection between the two problems then.

waiting for my pm.....................

BigErn

He's cheap and welcomes all colours creeds shapes and sizes, no need for boost, Pete has immense THRUST

jacko

just unplug it see if it has boost again

pete mcrash

iTrader: (1)

so have ya done what i said yet.......

pete mcrash

.....doesnt work fella......u've got ot take it apart......

jacko

yeh but better to try it than trace wires or easier still just try another on it first

BigErn

Just put it away for the night, plugged the idle (4000rpm) valve in again and nipped it round the block. Still low boost. Quickly checked the plugs on the idle valve and amal. Both have 13.4v and 0.5v when engine running. Thats all Im doing for today.

To the fridge.........

jacko

you wont fit your best having a shower#

BigErn

Ill make room by drinking the ONE bottle thats in ther

To the shop..........
