Hi like minded community! I’ve used google and kept seeing your forum popping up, very helpful so decided to join. Need a wee bit of help, I’ve found a Lucas part behind my instrument panel, behind speedo, number on it is 37800A 4886 but can’t find reference to it anywhere! Looks like a rectifier but it’s unplugged, five wires. Wouldanyone be able to let me know what it’s for?
