Great to see there is still some interest for the relay! Life got a bit in the way so the progress has been slow, but it is not dead.
I plan to just mold the pcb and wire harness in polyurethane potting, to keep the environments out. Very easy to do.
It wont be so serviceable without creating...
@izula Thanks for the kind word! Glad you enjoyed it!
@Neilo Perfect, and thanks for the part number, that was a new one on the list, I will see what I can find out.
The samples of the new connectors are verified and worked like a charm, an order is placed on those so we are getting closer...
Posted an article about how the 28590-56100 works here: 28590-56100 Relay analysis - Electronics - Kofotronic - https://wiki.kofotronic.com/display/KOF/28590-56100+Relay+analysis
It is a bit of a messy read and could really have used some clean-up and better formatting, but I figured it should...
@Darkwing58 Cool, do you know what relay is in your car?
I have so far found out that 4 different Toyota parts are the same type, only difference are voltage and mounting bracket. This is good news for making a universal replacement,
One can also replace the older two relay design, but the...
Just a small update, I was able to source the original connectors, both the male used on the relay and the female for the harness.
This means that making a fully potted replacement relay that is a true drop-in suddenly becomes much easier and is the route I want to go for.
The connector...
@bcsteel Thanks! I will look into a replacement for the connector that is plug and play. The one on the relay is the easiest to remake, but I also think one need to have the other end available in that case. On my car the female end on the harness is quite badly corroded.
@BreckenridgeCruiser...
Do you know what part numbers your relays have?
I agree with you regarding a fresh molded one should be best. Would you be comfortable with replacing the connector in the wire harness with a sealed type or do you prefer to keep the open stock connector?
I also realized that people might get a...
Recently I was so lucky to get hold on a beautiful 1990 HJ60, my dream car for a long, long time.
As with many I have trouble with my Fuel control / EDIC relay.
There are used relay to be bought, some reproduction replacement to be bought, but I am not quite happy with either solution. Used is...
