Sometimes, when starting the engine, your starter's starting circuit closes as expected, the retractor clicks and it starts spinning, but it feels like it does not have enough current. What reasons can be, and if this is due to the retractor relay, can it be disassembled?
Instructions
Step 1
The reasons for this phenomenon may be the attachment contacts of the power wires on the body of the retractor relay, which have oxidized or burned inside the retractor itself. And also the worn out starter brushes.
Step 2
To thoroughly understand and find out the cause, first remove the starter. If it is inconvenient for you to unscrew the third bolt from the starter mount with an open-end wrench, take a 13-point head, an extension and a ratchet wrench. Although you may be able to remove the retractor relay without removing the starter from the car.
Step 3
If you nevertheless removed it, then make marks on the case cover and retractor with a pencil so that when folding you will not have any problems.
Step 4
After that, remove the retractor relay and disassemble the starter. So you can make sure that everything is in order with the brushes, they still do not reach the critical 10 mm.
Step 5
If you have already removed the starter, then disassemble it completely, carefully check everything and lubricate it. Both lithium and graphite grease can be used.
Step 6
The solenoid relay is considered to be non-separable. Two screws can be unscrewed at the ebonite cover, but it cannot be removed, since two soldered wires interfere. But you unscrew the two cross screws and unsolder the contacts with a soldering iron. Just so as not to damage the sealing gasket, carefully pry off the cover with a thin screwdriver. Do this very carefully. And it can be easily removed.
Step 7
After disassembling the cover, you will find out the true cause of the defect. If the contacts of the retractor are burnt, then it is necessary to clean them well. Repeat this procedure even if they are okay, but only slight traces of erosion are visible. And even if there are no traces of obvious dirt on the contact group itself, perhaps it is not the power contact that is in a bad state.
Step 8
Be especially careful during the assembly phase of the assembly. Indeed, if you tighten the nuts on the copper bolts forcibly, you can damage the cover. If such a nuisance happens, seal the crack with epoxy resin, and fix the fiberglass on top. Although this is, of course, a temporary measure.
Step 9
Carry out the rest of the assembly in the reverse order. And after checking the starter for operability, be sure to generously lubricate all external contacts with lithol so that they do not oxidize in the future.
