Since Freddy has not answered I have another question. Bought an almost new Mahindra 5155, it had set outdoors at the dealers last winter. Had some, after market, LED light installed. Tractor works great, but no lights except the ones with independent switches(4 ways and work light and LED's). I have checked the fuses, they are mini's and difficult to remove and check, all appear good. The $300 4 way light switch, turn signal, horn and high/low beam headlights, may well be the problem, but changing it is a last resort. There are relays in the fuse block for high beam lights, low beam lights. How do you check those relays?
