Hey for your power steering pump I found that you have to lossen all of the blots that hold the pump on. To move the pump itself. Even if one bolt was still tight it would not budge. Thats what I found with mine anyway. There are a good number of bolts to slacken off

 

yeah i got the pump to the point where it was "loose". It was rocking back and forth along the adjustment bracket... the grove the tensioner bolt moves up and down in just wouldn't let it move any further away from the crank pully. May need to fabricate a new bracket or something. It took quite a smack when it hit the deck the other week so i may have bent the bracket or something.

I have a spare bracket if you want it?

hmmm tempting... you have pm!

ok, so I changed the voltage regulator on the alternator and I'm still not charging the battery...

 

Got out the multi-meter and measured the following.

 

1/ battery voltage of about 11.9 volts and going down with the engine on.

2/ Voltage from the positive end of the alternator and the negative end of the battery is about 15v and now holding steady.... What?!

 

I don't get it... The battery is capable of being charged because you can hook up jump leads and charge it that way no problem. Also, the alternator is kicking out a steady 15volts. Why does the battery keep going flat!!! :scratch:

 

 

HELP!

like I said, diode plate on the alt is probably knackered, inside the alternator is a set of thumping great diodes configured to rectify the voltage to DC, if one or more of the diodes that makes up the set is faulty you won't get the right voltage from the alternator and all sorts of wierd things will happen, sometimes even the alternator discharging the battery over night. You can sometimes even feel that the alternator is warm in the morning before the engine has run suggesting draining of the battery.

Also, have you tested the battery with a heavy drain discharge thingy, quick fit type place should do this free for you, just to make sure the battery is healthy.

I've got a new alternator to put in so I'm just going to do that i think. I havn't been able to test the battery properly no but I think unless i can give it a good charge soon then it may well get knackered. It's only a few weeks old but it's been fully flat a few times, now.

Hi Alex, sorry if it's been suggested before, but I would also look carefully at the earth points and the feeding wires underneath the insulation, to see or measure if they have gone bad. 15Volt sounds a little high in my ears, as there's a chance it will be overloading the electrical system. Once had that on my suzuki (mc) and it burned al the bulbs.

It was caused by the rectifier diodes being broken.

On my even older suzuki (mc too), I had a fire in the wires while driving through Les Voges into France. Had to pull it many miles ;) Exactly the same cause as above - dead diodes.

 

Cheers,

Redfox.

not checked the earths but I'll do that at the same time as I change the alt over... I can't hurt to swap them over anyway

I'm going with davidwort here (not like that :camp: ) when he says it could be the battery. An alt supplying more volts than the battery is reading across the terminals has always meant a dead battery for me in the past.

From what I read you're loosing 3v between the alty and battery, put the pos lead of the meter on the alty and neg lead on the pos of the battery with the engine running if it reads around 3v there's an issue with that lead or its connections.

I already did that and it read 15volts positive alternator to negative battery

Alty pos to battery pos (not neg)

 

This is to check for voltage drop from the alty to the battery lead and its connections, if you see the missing 3v you have an issue with the lead or its connectioins.

Found the problem i think... I had a thought to myself and it went like this:

 

I'm reading 15 volts from the alternator to the battery but that's not current... that's potential difference (sounds obvious to some maybe but not to me...) soooo, maybe the earth's are dodgy?

So... I checked the earths. I dismissed these originally because I could hear the "click" noise when I turned on the ignition. so I left it.

 

Had a look last night and found the starter motor earth is almost completely hanging off..... only a few threads of wire hanging on. I hope this fixes the problem but I'll let you all know tonight.

 

I'll fix this tonight and hopefully that should be it.

Fixed! Just that loose wire and a new voltage regulator! Now a healthy 14.5 volts across the battery :D happy days!

Proper job... :thumbleft:

Just reading through your corrado experience and I must say you've given me some new found motivation.

Cheers buddy! I'm glad you found some motivation! I think I'm starting to run out :lol:

great news AngloScot!!! I love the simple fixes, esp when we know they could be a new block or something insane.

[Alex_G60_Fanatic 0]

Right Sooooo, I have a new power steering belt for an 8v golf. Same profile but 12mm shorter hopefully will be able to tighten this one up.

 

Also, have been experiencing a distinct lack of power and this could be one of three things...

 

1/ I didn't tighten the alternator properly when i fixed it the other day and the belt isn't torqued correctly as a result.

 

2/ the charger is slowly dying. I know it's loosing oil already... This might be time to declare of road.

 

3/ i have an unknown problem... Boost leak, ignition problem etc

 

I'm having a look over the car tonight so I'll let you guys no what I find. :)

Well I had a look over the car. That 8v belt did the trick on the power steering. Just helped because I think the bracket the PAS pump sits on is slightly bent, it's tightened up nice now and the power steering is working a treat.

 

As for the lack of power... I tightened up the alternator... the drive belt from the pulley looks fine and nice and tight so i think it's probably my charger... I'm going to just try and drive the car less until I get the money to service it.

My knowledge of the G60 is limited but I think you can check the boost of the charger using the MFA. Link

Indeed you can, shall be doing that this weekend ;)

Alright treacle! I never thought I'd see you on here again!

 

The Motor is ok... Got loads of things still to do but at least she drives about now. Hows yours? You still thinking of getting rid?

[Alex_G60_Fanatic 0]

Well... I was going to check the steering issues and the boost levels on Wednesday because i had a few hours spare in the afternoon but Instead i had to take my poor little ferret to the vet and sadly put her down :(

 

not very happy, she was only 2 years old... sad day

Sad times, hate those visits to the vet. RIP
