What have you done to your DeLorean today?

I could power that with engine run voltage but then you don't get the bulb test light.

DMCH 140 amp alternator? Mine does the same, and for some period of time a few years ago would continue even with the key off. It resolved itself on its own (knock on wood) but I know I read where at least one other had the same problem and had to replace the alternator.

On rare occasions my DMCH alternator makes a little whining sound after I have shut off and removed the key from the car. If I hit the brake pedal, it stops. Probably has happened at least 10 times in the past few years.

Why? I'd like to know but it's not keeping me up at night

Yes. It is the DMCH 140 amp. It's the one that would flash and error code if you don't connect the sense terminal to the battery. Don't know if it always made that whine.

Ah ha! A brake pedal quick fix. I'll have to remember that if it starts again!

7/26/2025...... Replaced the Fuel Filter. Surprisingly easier than expected by not removing the compression fitting (elbow) from the hardline.

That little job was long overdue by 18,000 miles or... 5 years. Whoopsie!

Aug 2nd - Aug 4th (holiday Monday in Canada)

#5637 got a working stereo powered by a new auxillary fuse panel w/dedicated accessory relay.
Waiting on speakers as it turns out the 20 year old Pioneer speakers installed in the car suck.
Will post a writeup when I'm done.

Also fixed a slight coolant leak at the front passenger rad/bleed hose by tightening the clamps. New hoses, new clamps. Sometimes they need a snugging after some heat cycles.

Over the years I would look at my Interior Vinyl always wondering what it looked like when new. The Vinyl always had a brownish tinge which I assumed I was stuck with being a 44 year old vehicle. Well, after replacing the vinyl on the RH knee pad a couple weeks ago with the new cover kit from DMCH, Which looks great btw. I realized just how off the old vinyl looked against the new vinyl. On a whim I decided to see if the Door vinyl was cleanable. I happened to have a detailer recommended product (GTECHNIQ Tri-Clean) on the shelf I?d bought for cleaning the white interior of my Daily Driver.

Holy smokes! I couldn?t believe the difference.

This is a comparison on a half cleaned upper door panel.

Now it's time to put new foam in to give some definition.
