Wanted: Power posts for Lexus GS450h inverter.

Hi,

Does anyone have a pair of the brass power posts required for the GS450h inverter to squirt power in past the IGBT and Coil?


Thanks,

Andy.

I bought some brass stock to make some, and when I finally get to it I have enough for a spare pair... I’ll post back when I make them

I got a good start making the power posts before someone pointed out that brass has much less conductivity than copper (about 1/3)... I'm not sure if I'll continue down that path, as they also pointed out that using readily available aluminum spacers with a longer bolt will be a LOT less work.

…..aluminum spacers with a longer bolt will be a LOT less work.

Watch out, don’t want to be mixing dissimilar metals, especially for a HV connection. Lots of galvanic corrosion

Copper and aluminum are not a good combo.

Do you know what are the OEM bolts made of? I'm pretty certain they're neither copper OR aluminum, but the buss bars are definitely copper

copper or zinc plated steel
