Re: Imiev repair - precharge resistor

All the contactor coils ... read 36 Ω ± 0.3Ω. ... Doesn't seem to be carried by digikey or rs components, so it might be tricky to track down. Digi-Key and Mouser stock the single-contactor models in the G9EA series, like this one: https://www.digikey.com.au/product-detail/en/omron-electronics-inc-...

Re: Imiev repair - precharge resistor

I guess the other way to work it out would be based on the charging time and capacity of the inverter supply smoothing capacitor. There is a trouble code for too long a (pre)charging time (P1A15), but the manual I have doesn't say how long. Given the time before the main contactor disengages withou...

Re: MY FIRST BIG BLADE PROBLEM

It could also be a problem with the motor itself. Weber had two problems with his MX-5's third party power steering motor; there is a small chance you might have a similar problem. His main problem was that the brushes were not centred on the commutator, which he fixed with some veroboard acting as ...

Re: MY FIRST BIG BLADE PROBLEM

I wonder if the auxiliary battery might have died, or become weak. Perhaps the steering pump controller decided that the battery wasn't up to the load.

But power semiconductors in the steering pump motor controller seems more likely.

In the article, they talked about solid state batteries as the next big thing, but also as if they are completely different to present lithium ion batteries.

I read on other posts that there is an error90 for some inverters. Is mine can be blocked by this error with the 73 firmware.? With your older hardware (not as old as mine), the only way you'll get error 90 is if you use factory firmware 73.00 or later, or if you use the now-obsolete patched firmwa...

Re: HOW LARGE CAN I CHARGE?

Search for 'modular EV power AVC2'. You just add it to your car J1772 inlet socket and you are good to go for any AC EVSE. I've seen this on a recent Blade. If the car has a J1772 socket, I assume that it would have the ACV2 gizmo to make it work on any type 1 (J1772) EVSE. [ Edit: or indeed, other...

As a point of interest, why do you avoid single phase EVSEs? Is it because you have three on-board chargers and will load up the supply so much? But my understanding is that the Mennekes [ edit: was J1772] protocol will only allow charging up to the level that the EVSE is designed for and can comfor...
