Title: loose battery terminals
Post by: shifty on April 16, 2013, 08:04:33 PM
Got my FD today and already having issues I went to pull the car out of the garage, the imobiliser disengaged I turned the key dash came on the as I turn to start it dies, ok I thought maybe its a flat battery so I went to remove the batt and get it on charge and the clamps where fully tightened but slipped right of.
so I was hoping someone has some advice or an idea on what to do ive seen the JDM to euro adapters but surely being an imports my terminal would fit the smaller pins.

You can make the terminals grip easily. I did it on an older car and my old 8 did something similar.

All you need to do is open up the clamp that is a little loose and use something between the clamp and battery terminal to take up the little bit of slack. I think I used and old metal shaft from a rivet so when you tigten up the battery clamp it takes up the slack and grips into the terminal.  The rx8 I had used a small screw to do the same thing.  It can be used as a temp or permanent fix depending on how perfect you want it all to be

I want a solid connection but yeah will try that tomorrow ive ordered some conductive sleeves that may do the long run I just hop its that which has caused the lack of power and not any other issues its already sizing up to be a money pit.

Pop a couple of washers (M5 I think) on before the nut, should be fine then :)

yeah been looking at them as I used something similar on my RX8 after the garage trashed my oem clamps but the negative on the seven isnt on a lug its crimped direct to the clamp so would nee to check slack.
