Minus the common experience:
*Stiff rear spring
*Rear brake pipes corrosion
Cosmetic wise, without a code reader to hand, as im not going to short the pins and count...
I've got a little bit of ticking near the fuel injectors/possibly sparks/dissy when running and the idle is occasionally a very little bit lumpy (20rpm max), the accelerator when pushed very gently but constantly theres a drop in voltage by a volt --- is that usual for an initial draw? and when released from about 1600rpm within a couple of seconds or so, can almost cause a stall or at least a little engine judder. (possible its a valve/sensor readjusting or the alternator compensating) --- never know properly without a code reader, a cheap ELM327 (version 1.4) interface has been ordered.
I appear to have become a little paranoid about a few things to diagnose this issue, so feel free to send a virtual slap...
Heres the electrical problem I'm having don't know if anyone else has experienced this, and this may be a little too techy for this area, if so accept my apologies and feel free to move it elsewhere:
X16XEL engine, 2000 Astra G 1.6i 16v CD (with the KWP2000 MULTEC(H)/X16XEL ECU)
Seemingly dead battery overnight phonomenon --- left the car with about 12v (its a brand new 12v battery)
hear clicking and very occasional whirring, when trying to crank it, ensured the alarm and immoby isnt on, radio doesnt have a remote line pin connected (so only starts on ignition) .... I've checked to make sure glovebox, boot and interior lights are going out fully.
Left it for about 18 hours, and its down to 9v, of course the drain leads to a dim interior light... it's a brand new battery, and a charger shows battery is full and it gave off about 12v, so i've taken it out, charged it overnight for a slow charge...
It could be the new battery being faulty... however im not so sure... as the new battery was brought(with manufacturer plugs on) to fix the exact same problem?
Today, I plugged the batt back in, after cleaning the clamp terminals, Checked it gives off 12.7v on a multimeter
alternator tested on a bosch kit --- also testing the battery clamps are on properly.... alt and volt regulator passed fine, passed the ripple test, and under full load, its got a brand new starter motor, on a moderately warm day, probably worse on a cold day since the car tends to idle towards 1600rpm briefly til it warms up...
I've checked and cleaned battery connections and checked the earths (apart from gearbox earth) and that the fan does turn off after 5 mins or so (it only turns on if the ignition is on, and will only drain 0.3v when the battery is slowly discharging the alternator load, so that was due to be discharged anyway)
Maxiblade fuses burning like a gooden:
In the under hood fusebox, F7 - Electrohydraullic PAS fuse (80A) has burnt itself rather excessively, but not popped, it may explain why it felt light on one side of the steering occasionally and there was a steering judder at 70mph, which has now settled slightly... (mixed in with the rear spring stiffness, macpherson strut play at upper bush and the tracking or wheel alignment slightly off, but none of those are excessive)
the same has happened in the under dashboard fusebox: fuse 2 (30A for fan) and fuse 3 (40A for heated rear window) --- seemingly replaced before... judging by the spares the previous owner left in there!
I have, today, replaced those fuses and checked the others... fuses appear fine now
Also in the under dash fusebox, small amount of burning on the rear wiper and heated rear window relays, excessive burn on one of the windscreen wiper relay pins.
Bit of an intermittent problem with leccy window switches not 'auto opening', but will open and close fully, if the switch is held (probably unrelated).
Did have a small glitch where the boot locking motor would not open for love nor money, turning the key motor goes, but wouldnt unlock, a bit of wiggle has sorted that. (possible relation, but doubtful, never had the problem before, but time will tell if it's sorted)
I'm aware the cat. may need replacing some time soon (unrelated?)
Tomorrow if i have a dead battery or its lower than 11.5v, I'll be checking the under hood relays and replacing the windscreen wiper relay. Cleaning those battery terminals again so they're almost sterile and kept sterile! and tracing the battery cables and possibly giving them a test too! Fun!
Anybody got any suggestions on what this could be/might be?
Apart from the dead battery, gearbox to earth, relays, battery cables... where/how else to check without a code reader(til it arrives)?
