Replaced alternator in VP 5 litre but battery light still on

[88GreenVN]

Calais is go!

Went to Repco and Supershit auto, both said they don't sell the fusible links.

Went to Holden, no longer in service/supply.

Went to auto elec, he made up a new section of cable with the fusible link and terminal for $20.

Plugged it in and works sweet.

Starts strongly and runs smooth, and no more lazy hot starts from what I can see, something which is common in the 5 litre.

Even though it probably didn't need a new alternator, replacing the existing 15 year old unit made a noticeable difference.

Thanks for the help guys.

I may have to look into this for the lazy hot starts on my 5.0L

Now with it all working what does the trip computer voltage read now? My VN 5.0 sits at between 13.8 and 14 v from memory in diag mode.

Battery at rest with multimeter reads 12.57V.

Battery when idling with multimeter reads 13.48V-13.55V.

ECU when idling reads 13.4V-13.5V

ECU when I give it some revs reads 13.9V-14.0V.

So the new link improved the volts at idle and when cranking the starter. Sounds like a plan to me... One new link cumming up..

Well,

Drove it all weekend, covered a couple of hundred km's in it and it didn't miss a beat.

New alternator and fusible link also got rid of a engine miss that I used to get when sitting at the lights with the aircon on, or when the car was warm.

Made a noticeable difference in acceleration and fuel consumption too, got it onto the highway and got a lowest all time figure of 10 L/100km average before I went into traffic. Even still, my final figure was 11.5 L/100km, which is quite good.

Dissy cap, rotor button, new plugs and coil are next.

Came on here today to find a solution for this exact problem. After replacing that fusable linkage, car started first kick, no battery ight and battery went from 11.89 with engine running to 14.66. Also solved some strange misfiring problems that i'd been having and car now idles better as well.

amazing what 3 inches of wire can accomplish. cheers for the thread and the in depth discussion people. One less opportunity for a mechanic to anally intrude me.

hey what size fuse have u got in there mate? might give that link a go..

nah see the brown wire coming off the positive terminal? with the black plug on it. its about 2 inches long. take that off, and check continuity on it. if its got none, replace it

actually, is that what your brown wire plugs into? that black one? from memory mine goes directly to the voltage regulator on the alternator. mine looks different

Hey mate
Do you know where to find this fuseable link for alternator vt v6
I found a brown and purple wire connecter undone that car wouldn't start(alternator light coming on)
But i couldn't find a fuse
Thanks for your help
