Although I've long known that I'd probably have to do this one day, I've now noticed that a 30A relay is suggested. As I've got a set of (ex-VSX) 25A relays, I'm trying to work out if I could sensibly use one of these instead of waiting until tomorrow and buying one from a factor or auto-electrician.
This relay will have to switch the power for the blower circuit (Fuse #20 - 20A) plus the 'small' switching current for the heated rear window relay.
A 20A fuse will carry 30A forever without blowing, but relays aren't as forgiving of abuse. So although replacing failed relay is relatively easy, it would be bound to fail at a really inconvenient time like a sub-zero night when both HRW and heater are essential!
So, please can can anyone tell me with certainty:
- 1. What maximum current does the blower circuit draw?
2. What a typical switching current for a Xantia relay is?
3. Which of the following Xantia S1 relays is most suitable in terms of what purpose they are intended for:- 03.601 [Green] 25A single contact (N.O. - no pin 4)?
03.501 [Black] 25A changeover (pin 4 to pin 5)?
03.517 [Purple] 25A changeover (pin 4 to pin 5)?
- 03.601 [Green] 25A single contact (N.O. - no pin 4)?
