Peder, Installing an alternator will not make your lights brighter. The brightness depends upon the voltage delivered to the lights. 6 Volt lights require at least 5.5 volts to get to their design output. A generator in good condition will provide 7.2- 7.4 volts around 1,000 rpm. An alternator in good condition will provide the 7.2-7.4 Volts at a lower rpm. These voltages are measured at the voltage regulator battery seminal. Your lights may not be getting the proper voltage due to Resistance in the circuit. The voltage drop test that i described in my earlier post will help you isolate the circuit resistance. The tail lights and stop lights can appear dim due to the color of the lens. Some lenses are much darker than others.

I got the belts from a firm that sells belts , chain drives, for industrial use. I believe those numbers are the inside length in inches. you might try ebay.

Did you buy those belts at Mac's? Can't find them there, or any others for that matter...a part no. would help...not sure if these can be bought in Norway...thanks... Peder

Hi Peder,I used a Bando BX 53 for the alt. and water pumps and a B35 for the fan. This put everything right in the middle of the adjustment range. I'm sure your supplier can cross reference these #s to Gates or other brands.

Hi again! Regarding the alternator, Mac's ad also states that it is necessary to source a v-belt for this unit...do you have the part no. for that belt? Thank you. Peder

Thanks Cliftford! I like to keep my car as original as possible, but sometimes a change is for the better, and in this case, based on your happy experience, I will get in touch with Mac's...thanks again...Peder

If you're not worried about originality, an alternator is by far the best way to go. I recently bought one for my '48, and am happy with it. It is a 6v, pos ground, and is listed in Mac's catalogue, part# 32-12899-1, with bracket for $165.00.

Hi again! Had an "electrician" check the battery voltage. All is well, and the battery is strong despite its age. His suggestion for better and brighter lights was to use a higher gauge wire. So we connected a 6mm gauge wire and the brake/turn signals became much brighter!!! Also suggested was to look into a 6 volt alternator. Any comments on replacing the generator with an alternator? I see Mac's has this alternator, but only up to 1939. Thanks, Peder

Ron Francis, www.ronfrancis.com has 6 volt L.E.D. replacements. I think a clue to your taillight issue is where you state "requires stepping on pedal really hard". Your taillights should be bright no matter how hard you push down on the brake pedal. Also you state that your battery was replaced in 2007, it's 8 years old,I know it starts fine but it's time for a new one. I would do all of the above suggestions (except the 8V, the 6 volt system should be fine). I would check all the grounds first and wire brush or sand the connections.
