Frank Elder Posted February 14, 2021 Report Share Posted February 14, 2021 A 30 amp relay helps horns and headlights to be more efficient, so would it work on my D-24 wipers also? Quote Link to comment Share on other sites More sharing options...
plymouthcranbrook Posted February 14, 2021 Report Share Posted February 14, 2021 (edited) I wouldn’t expect your wipers would draw enough current to need a relay. Headlights use them so the full draw of the current to operate the lights doesn’t need to go through the dash switch. http://www.secondchancegarage.com/public/133.cfm Edited February 14, 2021 by plymouthcranbrook 1 1 Quote Link to comment Share on other sites More sharing options...
JBNeal Posted February 14, 2021 Report Share Posted February 14, 2021 Them electric wipers benefit from cleaning out the gearbox and refilling with JD corn head grease, as well as replacing the leads with new wiring...both repairs greatly reduce the electric motor resistance, which can really pep up the wiper action ? 1 Quote Link to comment Share on other sites More sharing options...

Marcel Backs Posted February 18, 2021 Report Share Posted February 18, 2021 Are you on a 6 or 12 volt system Frank? Quote Link to comment Share on other sites More sharing options...
Frank Elder Posted February 18, 2021 Author Report Share Posted February 18, 2021 Twelve volt my good man. Quote Link to comment Share on other sites More sharing options...
Sniper Posted February 18, 2021 Report Share Posted February 18, 2021 My problem when I went to 12v was that the wipers went into overdrive and I had to slow them down. Seems odd that yours are dragging. Maybe the suggestion of a good cleaning and lube has more merit that suspected. 1 1 Quote Link to comment Share on other sites More sharing options...
Marcel Backs Posted February 18, 2021 Report Share Posted February 18, 2021 (edited) If this is a period piece and it is 12 volt, it may be as simple as cleaning and lubing the gears in the mechanical drive. A dirty electrical motor may also be dragging it down which is common in these old wiper drives. Inspect and clean armature and commutator and check end play. Use isopropyl alcohol and a small brush or qtip to clean above as well as the brushes and any internal switches. This should give the wipers a little more pep ! Hope this helps you out man. All the Best, M PS did you test your wiper speed by disconnecting wires from switch and powering the motor from a direct 12 volts using a good heavy test lead?

Plymouthy Adams Posted February 18, 2021 Report Share Posted February 18, 2021 majority of drag issues in motor are related to rear bushing wear...or if not wear, will relate to being dry of lubrication and will need attention and if not soon attended to will accelerate the wear and prove then needing replacement and lube...this applies also to points of mechanical beyond the motor in bushings on the linkage and the towers of the wiper stems....many Mopar wiper stalks have screws that you remove so lube may be applied.... 2 1 Quote Link to comment Share on other sites More sharing options...
Marcel Backs Posted February 18, 2021 Report Share Posted February 18, 2021 my wiper pivot caps have a small screw you remove to oil the outside end of the mechanism. PA got it! I had a pivot cover missing on my D14 6v electrical wiper set up...try finding one of those. I think it's the hardest part to find for a 40 mountain goat. I ended up getting a pair machined and will post pix. As Plymouthy said bushings wear and lube are a must check. Also check for binding at link points and make sure you have felt isolator washers at pivot points. You will have your wipers able to handle Canadian rain storms and it might be a good bet considering the wacked out weather in the south!
