Alternator Replacement - Comments
#21
Ok, So the good news is I’m going from 12.2 to 14.2 V across the battery terminals with the engine running, but have the dash messages of battery not charging and a red light on the meter, even though reading 13V.
I read this in another thread to reset computer
remove the negative battery cable in trunk,touch it to the positive battery TERMINAL for 30 seconds.
am I reading this right.
with the positive terminal connected, I remove the negative cable and move it across to touch the positive terminal.

That sounds safer, but it hasn’t helped. An Road side assistance guy who was helping my neighbour said sometimes it takes the computer a while to sort itself out and as long as there is 14.2V at the battery it will be charging. I guess I’ll start driving the car and see what eventuates.

These cars do not play well with aftermarket alternators. It has often been reported here that while they usually do indeed properly charge the battery, they also leave the alternator warning icon on the dash permanently illuminated. Your best bet is to have your factory alternator refurbished with the proper Denso kit....

Update
So my battery has been charging fine, but still have the dash message battery not charging and the red light on the gauge.
I also went to use my heated seats and neither of them work. I rarely need to use in Australia, but they had worked before I refurbished the alternator. Is this related ?
I understood I had genuine Denso parts used.
If either of the two wires in the connector are damaged, would this be why I have the warning lights. Although I had difficulty removing and damaged part of the plug, the wires were intact and it definitely connected properly with a click to the alternator.
Not sure how I can go about solving

I guess you could strap the two wires together but then you wouldn't get a warning if the alternator did go south again...
Your heated seat issue is unlikely to be related.

Alternator replacement
Hi-I have a 1997 XK-8 coupe. Dont use just any Alternator OR the light will stay on and it will say "battery NOT charging" Even though it IS charging. There is a part in the geniune Jag units that is not in ALL of the. You can get the Proper Alternator from Welsh Jaguar in the USA. The only one that worked for me. My Alternator was FROZEN into the bracket. I ended up hammering the unit out. I don't recommend that. . The reason the light is on, is due to the improper unit. The Heated seats will ALSO be inoperative until you get the proper unit. Dont cross any wires to wire out the light. Get the proper unit. GOOD LUCK!!! Ben
