Hi Mark,

Great little product you've designed there, and cool way of testing with your Arduino car simulator : )

I forgot to update this.

It seems that one unit was destroyed or it failed on it's own and the tear down proved that.

The two new units cast much better, and tested just fine.

I arranged to visit and help see they worked correctly.

I fixed a couple of minor wiring issues that weren't incorrect, it's just that they might fail later.

When we tried the units, they also behaved strangely and worked with just the brake, or just the indicator.

After heading into some rabbit holes, the owner said he had the wiring diagram for the indicator unit somewhere and dug it out.

Once I looked at it carefully, I noted that it had the ability to feed the brake signal into it.

I hadn't realised it was from the USA and had the ability to combine brake and indicator into a lamp, but used a different flasher unit (one I've never seen here in NZ)

Once we removed the brake feed into the indicator unit, the whole thing worked properly !.

What a relief for both of us.

So it's always surprising what is going to bite you, and the 'never give up' attitude certainly wins .... eventually.

It also explains why I couldn't prove the fault on the bench, I wasn't simulating the exact conditions found in the vehicle.

We also added the necessary extra piece I'd built so the indicator stork flashes when they are operated.

The result was a very happy owner.

Hi Mark,

I know how you feel. When something I put together doesn't work right I am absolutely obsessed with finding out what it was. It is a point of pride if nothing else. Fortunately over the last 4 years I have had you guys on E14 to help me pull the bacon out of the fire on numerous occasions. Thanks for sharing the adventure you had with these projects with us.

John
