Starter relay is shown on parts scheme 28300 RELAY ASSY, STARTER, but has got no part number for SERA01 SERA02... only SERA03 /28300-10020 (12V Denso 156700-0503) for fuse and relay block /82660-10130 similar relay to check is: 85915 RELAY, MAIN /90987-02006 -> relay has no problem, because I have solenoid sound on each ignition key turn to "start" there is alternative solution to install mentioned relay on SERA01 additional: to clean ground terminals on both engine sides L\R |

Replaced starter to 28100-11020 (0.8kW) - original for EXY10. was 28100-16230 (0.8kW). starter /28100-10060 fits Sera 1kW Need lower starter bolt /91612-61045 and high load (80A) cord connector (from battery to alternator wire) as specified on fuse box -> this part still needs to be replaced, both wire and terminal measured: Accumulator is 12.29V and above in standby (new battery Varta 5634010613162 "silver dynamic" 63Ah gives 12.6V in installed state, and 12.8V during disconnected from car). Engine starts normally now each time - problem almost solved Real problem of starter was in wiring and oxidized terminals: install more powerful and solid connectors, hide from moist with insulating cover, apply protective paste to battery and lock contact pads as well. clean inside of starter dust see black wire from battery |
