ParticipantCar has been showing EOBD light but only intermittently. Now, won’t start with awful ratcheting sound and NO/ASR showing on dash. Any suggestions appreciated. Car regularly maintained and ran well a week ago.

ParticipantMemories of the sprung ratchet on a starter motor thrower?

ParticipantHi Richard,
Last time you used the car did the NO/ASR come up on the dash or has it only come on now you try to start it?
When you a say a ‘ratcheting’ sound is it actually trying to turn the engine over when trying to start? How old is the battery?
What year is your car? If late 2001–> (it depends on chassis number) it may have a proper OBDII socket (2 rows of 8 holes) on a cable under the steering wheel tucked up behind the dash. If earlier it will be ‘interim’ socket. Tony on this forum can provide advice on that.
If it does have the proper OBDII socket then if you can find someone with a reader you could find out the error codes which will have caused the intermittent EOBD faults, that may provide a clue.

ParticipantChris raises a valid comment, if a really loud sound then… 3200 start motors are notorious for ‘giving up’ (sitting in the engine vee at the back – bad place!).

ParticipantAlway check the battery first, if you suspect it’s the starter motor these can be repaired at a reasonable cost. http://www.maseratished.co.uk, Mike looked after my old 3200.

ParticipantHi Graham
Thanks to you and to Chris for the impressively prompt replies.
NO/ASR has only come up this once. Very loud ratcheting sound but not trying to turn the engine over. New battery Aug 2017. New starter motor Aug 2019. Appreciate the need for reader with full rather than partial analysis capability in order to diagnose intermittent EOBD warning light illumination. Putting the battery on charge as wondered whether ANR actually meant (duff) alternator – although would have expected the warning to show when engine running. Will let you know. Car gets a 6 mile run every week or so with brakes and engine up to temperature.

ParticipantChris, Graham and Tony,
Battery charged – took longer than expected. NO/ASR flashed up then cleared and car started instantly. Throttle fully responsive and no EOBD warning light illuminated. Taken for an ‘essential’ run and noticed ammeter at 13 but at one stage waning alarmingly then back up to but no more than 13. Battery on charge again and depending on length of charge will suspect the alternator or connections? Thanks again for help. Tony, thanks for M/Shed details which is 60 miles from me. The car has been looked after by Giallo for the last 15 years (which is still 40 plus miles away).

Participantyou prob know all this but…. good alternator should show 14.1-14.7v with the engine running from a multimeter on the battery terminals– if you load it by turning on the headlights ,switch on the fan full on and radio it shouldn’t change much– in any event should never go below 13v- if it drops then you have a prob. … and doesnt take long to do

ParticipantThanks Chris. Know some of it but helpful to have the detail.

ParticipantHi Richard,
You are best to check the voltage at the battery – 3200 voltmeters are notoriously unreliable at showing an accurate value.
Assume it is sitting just past vertical most of the time when about & about (which is 13v)?
Mine often hovers between 13v & 14v, and as Chris says shows 14.5+ at the battery terminals with my multimeter, and has been known to dip to 10v for obscure reasons I cannot fathom!
It does seem that your battery may have been run down and that was the problem, so it may be worth trying to find out what caused that in just a week. On a different post, when I first got my 3200 (15 years ago) I had a faulty RAC Trackstar that took the battery out in just 3-4 days. Other things to check (apart from obvious interior lights) are memory switches etc. on the seats that can get stuck.
The good news is you did still have some power in the battery as the dashboard light came on. If it had been totally depleted that would affect life of the battery even after fully charging.
What year is your car?
If it is a late one with the OBDII connector as I described earlier, it will probably also have a battery disconnect switch in the boot (right hand side behind the battery flap – a round black knob about 3cm in diameter to the left of the fuses.
If page 83 on your 3200 manual describes it, then you have it.
I have shown at least 3 people this who were not aware of it as it was only put on the very late 3200s and it seems some had the older manual without the descripton for it (so Maserati!!).
Mine has that and I just switch it to disconnect when leaving the car for more than a few days, and just run my Optimate battery conditioner on the battery twice a year to confirm the battery is in good condition. Last battery was 12 years old when I replaced it, and only then because I wanted to ensure reliability.

ParticipantHi Graham,
Exceptionally helpful.. Battery now fully charged and will carry out the voltage checks tomorrow. The car registered 06 02 2001 so probably a 2000 production model. Chassis No is ZAMAA38C000003938 and I’ve owned it for ten years. It does have the battery disconnect switch in the boot. Have not used it for fear of having to reboot the Becker Cascade 7944 fitted by previous owner if I do.

ParticipantAhhh yes! I do know the security code for my (factory fitted) radio/Sat Nav system, so have to enter that every time.
The sat-nav is fun, as it is technology circa 1999 and uses a small LCD panel to show the directions on.
To be fair, it does work, and we have used it sometimes rather than boot up our portable Garmin unit!
Shame the previous owner did not give you the code for the Becker.
Would have thought there are many ‘reputable’ people out there who could find out the code for the Becker unit (and many ‘disreputable’!!).

MMSA-radiocode website? No idea if its good
24th May 2020 at 1:02 pm #13319richard-monk
ParticipantHi Graham,
No, I have the code but it does also mean inserting a start-up CD and I think I had to select language as well.
Thanks again for your helpfulness.

ParticipantGraham and Chris,
Car started instantly but EOBD light illuminated. Multimeter gave a strong reading of high 14 and virtually no fluctuation when lights and fan switched on. Reassuring. Despite EOBD warning, throttle fully responsive. Car driven,engine stopped and battery only showed reading of 13amps. Expected more. Will check again tomorrow and decide if battery at fault. Car started again and engine speed rising and falling between 2000 revs and tick-over with no input from me or effect when I pressed the throttle. That’s a new one on me and got to be EOBD fault generated. Again, grateful for your help and links provided.
Richard
