Batt Tender
Powered up my Vecter 1/2 amp battery tender on my 07 Coupe last week. Today I found the tender making a rapid "clicking" or rattling noise along with both green and amber light glowing. This condition continues for about 30 seconds - then only green light glows. Then the tender repeats the above.
I connected the red clamp to + battery terminal, the - on an exhaust manifold bolt.
Does anyone have a clue what is causing this?

The only things I can think of are:
Bad connection to battery/car.
Bad wire to or from tender.
Defective tender.
99% of the time when I have a problem, it's #1.
Once in 30 years, it was #2.

Why wouldn't you want to connect tender to (+) and (-) of battery.
Try that first to see if the tender does the same thing. If it does, maybe the tender is going bad.

I guess I'm not sure what the reason would be for not connecting the negative clip to the battery anyway.

We are supposed to connect positive to the battery, then negative to a ground somewhere else so any spark will be away from the battery. I will plead guilty to not always doing it that way.

Right GJ, instructions for the tender call for - connection away from battery.
I removed the negative connector from the exhaust manifold bolt, cleaned the bolt head with sandpaper. I did notice a bit of surface rust - not much (I cleaned the bolt head last year). After applying a little oil on the bolt head to prevent further corrosion I connected the negative clamp and powered up the tender = working fine. I didn't think corrosion would be an issue as I cleaned the bolt last season and never drive in the rain, but I see humidity is a factor. From now on I'll clean the connection every season.
Thanks guys.
