Hello,
I think solved this frustrating starting problem that has been haunting my Max until recently. As this is the first year January model, some improvements have been done. They are:
1) To solve the charging problem, made
- Crimp fix
- Changed the regulator / rectifier into the newer model's (1993-) one
2) To solve the starting power / starter clutch slippage problem
- Changed the battery into YTX24HL-BS (nominal values: voltage 12 V, capacity 21 Ah, cold cranking current (=starting power) 350 A (DIN) and 567 A (EN)
- For comparison, the same values of the original type battery are: voltage 12 V, capacity 12 Ah, cold cranking current 130 A (DIN) and 210 A (EN)
- Changed the whole cabling (both + and - sides) between the battery, starter relay, starter motor and grounding. Same time increased the cable diameter and soldered all the joints. Further, soldered together all the grounding cables so that battery minus, engine, frame and starter motor housing are all connected directly by the grounding cable. Also drilled there a hole for extra ground connection bolt into the starter motor housing in order to get the grounding cable connected good.
- Cleaned the M8 threads in the flywheel, where the starter clutch is connected via the three bolts. Now this is important operation! As the bolt ends have been hit at the factory to prevent them getting loose, this usually messes the threads up when they are released during the starter clutch disassembly. If the thread is not in good condition (i.e. the new bolt can not be twisted in just by fingers), it's better to be cleaned by the proper thread fixing machinist tool. Only after this it can be tightened accurately into the specified torque.
If you take a look at the CCA values, regardless of the measuring standard, the nominal starting power is 2.7 times higher than in the original type battery. Meanwhile the Ah capacity has also grown from the original 16 Ah to 21 Ah, which is good thing as well.
This battery is of about the maximum physical size that can be installed into a V-Max. To do this, you have to take the plastic battery box away and cut all the walls. Then install the bottom back, and if you want, the front and/or back wall then. This I believe is not necessary, as the battery is not moving very easily due to it's big size.
Oh yeah, and the cost. It was 120 euros. So if you have starting problems, the solution is right here...
