Is this relay (#89 cut-out of start-up with battery charger) suppose to be warm all the time?
It should only be energised when the OEM charger is in use. If you're not using the OEM 4 pin charger plug, it shouldn't be energised. What sort of charger do you have? During normal off-charger running, it should be deenergised, allowing the starter relay (#91) coil to energise during start. i.e. during start, it should momentarily have a small current flowing through it to the starter relay coil. Could it just be warm from heat conduction or is it at hot as, say, relay #90? That should be toasty during normal running ops. https://www.dropbox.com/t/2T3gf7MAuxBYIDQu (see 5H fuse/relay block) (Spider diagram uploaded ... as it matches your relay numbers) Image Unavailable, Please Login
P.S. I mentioned this relay here (to you): https://www.ferrarichat.com/forum/posts/149031596/ but I didn't realise at the time that you had different relay numbers. I was waiting for you to confirm that the relay numbers in the previous post were the same as on your car.
Ian: You are just a wealth of knowledge!! I am using the OEM charger and leave it connected all the time. I took it off the charger for a while and it (#89) still felt a little warm and that is what concerned me. I just changed relay # 91 with a new one but have not taken the car out for a test drive to see if my starting problem when hot re-occurs. Also, my relays are the same as your diagram. Thank you again for all your info.,
Yes, I totally agree what you said about Ian. So much electrical knowledge Image Unavailable, Please Login Usually, when a relay is not in service (not required to be energized) and found to be warm is a sure tell tale that it is fully or partially latched. That is sometimes how you find a source for battery drain; feel the relays
nah…. I just know how to read my own home made diagrams. It’s the hidden bits inside the components (and the mechanical bits attached to electrical bits) which baffles me
