Brake OH, Health Check, etc 01

Rate this Entry














Started to servicing another NSX from last week.
The service menu was Health Check combined with annual service plus compression check but now it's more of
emergency full brake service due to leaky master cyl and dragging brake caliper.
















The owner told me that he had excessive current draw while parking the car and killed his battery.
Also told me that when connected to the battery conditioner, it stayed in charging status for days and conditioner itself got very warm/hot.
But eventually, the issue disappeared and no longer having any issues.

On arrival, thought about measuring the dark current but before disconnecting the battery that may reset something,
checked the well-known sticky relay issues around the car.

Nothing obvious and all relays were fine.















Connected to the battery conditioner and as owner reported, no more issues and it went into conditioning mode within a few hours.























As the battery holder bracket was installed in the wrong orientation and in fact, not secured properly, I have to disconnect the battery at some point so
that will be a good timing to measure the dark current but without being able to re-create the battery drain issue, not much point.

The posi terminal was really close to the bracket.
As pointed by my finger, this cut out should be placed at the posi terminal.
Otherwise, it's too close to the posi. terminal and also the geometry of the holder stay/bracket won't let you secure the battery body tightly.

Now it's installed in the correct orientation and even you shake the battery, it doesn't move at all.
